The QRW series provide up to 40A output current in an industry standard quarter brick, which makes it an ideal choice for small space, high current and low voltage applications. The converter uses synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 91% at 3.3V full load. Thanks to the ultra high efficiency of this converter, the power dissipation is such that for most applications a heat sink is not required. In addition, the QRW-series supports future migration of semiconductor and microprocessor supply voltages down to 1.0V. * UL is a registered trademark of Underwriters Laboratories, Inc.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with a maximum rating of 10 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data for further information.

Highly inductive source impedances can affect the stability of the power module. For the test configuration in 49, a 33 F electrolytic capacitor (ESR < 0.7 W at 100 kHz) mounted close to the power module helps ensure stability of the unit. For other highly inductive source impedances, consult the factory for further application guidelines. Note:Measure input reflected-ripple current with a simulated source inductance (LTEST) of 12 H. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 49. Input Reflected-Ripple Test Setup. COPPER STRIPS VO(+) Output Capacitance High output current transient rate of change (high di/dt) loads may require high values of output capacitance to supply the instantaneous energy requirement to the load. Tp minimize the output voltage transient drop during this transient, low E.S.R. (equivalent series resistance) capacitors may be required, since a high E.S.R. will produce a correspondingly higher voltage drop during the current transient. Output capacitance and load impedance interact with the power module's output voltage regulation control system and may produce an 'unstable' output condition for the required values of capacitance and E.S.R.. Minimum and maximum values of output capacitance and of the capacitor's associated E.S.R. may be dictated, depending on the module's control system. The process of determining the acceptable values of capacitance and E.S.R. is complex and is load-dependant. Lineage provides Web-based tools to assist the power module end-user in appraising and adjusting the effect of various load conditions and output capacitances on specific power modules for various load conditions. 1.0 F 10 F SCOPE RESISTIVE LOAD VO(-) Note:Use a 1.0 F ceramic capacitor and a 10 F aluminum or tantalum capacitor. Scope measurement should be made using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module. Figure 50. Peak-to-Peak Output Noise Measurement Test Setup. SENSE(+) VI(+) II SUPPLY VI(-) CONTACT RESISTANCE VO(-) VO(+) IO LOAD CONTACT AND DISTRIBUTION LOSSES Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950, CSA C22.2 No. 60950-00, and VDE 0805:2001-12 (IEC60950, 3rd Ed). These converters have been evaluated to the spacing requirements for Basic Insulation, per the above safety standards and 1500 Vdc is applied from VI to VO to 100% of outgoing production. For end products connected to -48 Vdc, or -60 Vdc nomianl DC MAINS (i.e. central office dc battery plant), no further fault testing is required. Note:-60 V dc nominal bettery plants are not available in the U.S. or Canada. For all input voltages, other than DC MAINS, where the input voltage is less than 60 Vdc, if the input meets all of the requirements for SELV, then: SENSE(-) Note:All measurements are taken at the module terminals.

Output voltages will remain withing SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters. One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. n For all input sources, other than DC MAINS, where the input voltage is between 60 and 75 Vdc (Classified as TNV-2 in Europe), the following must be adhered to, if the converter's output is to be evaluated for SELV: n The input source is to be provided with reinforced insulation from any hazardous voltage, including the AC mains. One VI pin and one VO pin are to be reliably earthed, or both the input and output pins are to be kept floating. Another SELV reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module's output. n n The power module has ELV (extra-low voltage) outputs when all inputs are ELV. All flammable materials used in the manufacturing of these modules are rated 94V-0, and UL60950A.2 for reduced thicknesses. The input to these units is to be provided with a maximum 10A normal-blow fuse in the ungrounded lead. Lineage Power 28 Data Sheet June 15, 2009 Feature Descriptions Overcurrent Protection QRW010/025/035/040 Series Power Modules; dc-dc Converters 36 Vdc - 75 Vdc Input, 1.0 to 12 Vdc Output; 10 A to 40 A the Feature Specifications table i.e.: [Vo(+) - Vo(-)] - [SENSE(+) - SENSE(-)] 10% of Vo, rated The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shutdown value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment (trim). See Figure 53. If not using the remote-sense feature to regulate the output at the point of load, then connect SENSE(+) to Vo(+) and SENSE(-) to Vo(-) at the module. Although the output voltage can be increased by both the remote sense and by tine trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim: the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure current limit for few seconds. If overcurrent persists for few seconds, the module will shut down and remain latch-off. The overcurrent latch is reset by either cycling the input power or by toggling the on/off pin for one second. If the output overload condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely until the overcurrent condition is corrected. An auto-restart option is also available. Remote On/Off Two remote on/off options are available. Positive logic remote on/off turns the module on during a logic-high voltage on the ON/OFF pin, and off during a logic low. Negative logic remote on/off turns the module off during a logic high and on during a logic low. Negative logic, device code suffix "1," is the factorypreferred configuration. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the VI(-) terminal (Von/off). The switch can be an open collector or equivalent (see Figure 10). A logic low is Von/off = 0 V to I.2 V. The maximum Ion/off during a logic low is 1 mA. The switch should maintain a logic-low voltage while sinking 1 mA. During a logic high, the maximum Von/off generated by the power module is 15 V. The maximum allowable leakage current of the switch at Von/off = 15V is 50 A. If not using the remote on/off feature, do one of the following to turn the unit on For negative logic, short ON/OFF pin to VI(-). For positive logic: leave ON/OFF pin open. Ion/off + Von/off - ON/OFF SENSE(+) VO(+) LOAD VI(+) VI(-) VO(-) SENSE(-) SENSE(+) SENSE(-) VI(+) SUPPLY II VI(-) CONTACT RESISTANCE VO(-) CONTACT AND DISTRIBUTION LOSSES VO(+) IO LOAD Figure 53. Effective Circuit Configuration for Single-Module Remote-Sense Operation Output Voltage. Output Overvoltage Protection The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold, then the module will shutdown and latch off. The overvoltage latch is reset by either cycling the input power for one second or by toggling the on/off signal for one second. The protection mechanism is such that the unit can continue in this condition until the fault is cleared. Figure 52. Remote On/Off Implementation. Overtemperature Protection These modules feature an overtemperature protection circuit to safeguard against thermal damage. The circuit shuts down and latches off the module when the maximum device reference temperature is exceeded. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. 29 Remote Sense Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections. The voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in Lineage Power Data Sheet June 15, 2009 QRW010/025/035/040 Series Power Modules; dc-dc Converters 36 Vdc - 75 Vdc Input, 1.0 to 12 Vdc Output; 10 A to 40 A Feature Descriptions (Continued) Output Voltage Set-Point Adjustment (Trim) Trimming allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-) pins. The trim resistor should be positioned close to the module. If not using the trim feature, leave the TRIM pin open. With an external resistor between the TRIM and SENSE(-) pins (Radj-down), the output voltage set point (Vo,adj) decreases (see Figure 54). The following equation determines the required external-resistor value to obtain a percentage output voltage change of D%.

Circuit Configuration to Increase Output Voltage. For Output Voltage: 1.2V, 1.0V The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shut-down value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment (trim). See Figure 53. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power.

Figures 57 through 64 shows the maximum current that can be delivered by the corresponding module without exceeding the maximum case temperature versus local ambient temperature (TA) for natural convection through 2 m/s (400 ft./min.). Note that the natural convection condition was measured at 0.05 m/s to 0.1 m/s (10ft./min. to 20 ft./min.); however, systems in which these power modules may be used typically generate natural convection airflow rates of 0.3 m/s (60 ft./ min.) due to other heat dissipating components in the system. The use of output power derating curve is shown in the following example. What is the minimum airflow necessary for a QRW035A0F operating at VI = 48 V, an output current of 23A, and a maximum ambient temperature of 70 C. Solution Given: VI = 48V Io = 23A TA = 70 C Determine airflow (v) (Use Figure 62): v = 1m/sec. (200ft./min.) Thermocouple Location Tref 2 The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components are mounted on the top side of the module. Heat is removed by conduction, convection and radiation to the surrounding environment. Proper cooling can be verified by measuring the temperature of selected components on the topside of the power module (See 56). Peak temperature (Tref) can occur at any of these positions indicated in Figure 50. OUTPUT Thermocouple Location Tref 1 Airflow Thermocouple Location Tref 3 INPUT Note:Top view, pin locations are for reference only. Figure 56. Temperature Measurement Location. The temperature at any one of these locations should not exceed per 1 to ensure reliable operation of the power module. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table. Although the maximum Tref temperature of the power modules is per 1, you can limit these temperatures to a lower value for extremely high reliability.

They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your Lineage Power System representative for more details. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.
