Description
The SW/SC series power modules are isolated dc-dc converters that operate over a wide range of input voltage (VIN = 18 - 36Vdc for SC modules and VIN = 36 - 75Vdc for SW modules) and provide a single precisely regulated output. This series is a low cost, smaller size alternative to the existing LW/LAW/LC with enhanced performance parameters. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency, typical efficiency of 86% for 5.0V/3A. Built-in filtering for both input and output minimizes the need for external filtering.
This product is intended for integration into end-use equipment. All of the required procedures of end-use equipment should be followed. * UL is a registered trademark of Underwriters Laboratories, Inc.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of complex 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 fastacting fuse with a maximum rating of 3A (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 sheet for further information.

Input Source Impedance
The power module should be connected to a low ac-impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 43, a 33F electrolytic capacitor (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines.

NOTE: Measure input reflected ripple current with a simulated source inductance (LTEST) of 12H. Capacitor CS offsets possible battery impedance. Measure current as shown above.
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., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE 0805 (IEC60950, 3rd Edition). If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module's output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true: The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains. One VIN pin and one VOUT pin are to be grounded, or both the input and output pins are to be kept floating. The input pins of the module are not operator accessible.

Another SELV reliability test is conducted on the whole system (combination of supply source and subject module), as required by the safety agencies, to verify that under a single fault, hazardous voltages do not appear at the module's output. Note: Do not ground either of the input pins of the module without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pins and ground. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. For input voltages exceeding -60 Vdc but less than or equal to -75 Vdc, these converters have been evaluated to the applicable requirements of BASIC INSULATION between secondary DC MAINS DISTRIBUTION input (classified as TNV-2 in Europe) and unearthed SELV outputs. The input to these units is to be provided with a maximum 3A time-delay fuse in the ungrounded lead.

Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will only begin to operate once the input voltage is raised above the undervoltage lockout turn-on threshold, VUV/ON. Once operating, the module will continue to operate until the input voltage is taken below the undervoltage turn-off threshold, VUV/OFF.
Feature Description
Remote On/Off
Two remote on/off options are available. Positive logic 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, device code suffix "1", turns the module off during a logic high and on during a logic low. To maintain compatibility with LW series power modules the Remote On/Off pin is optional for the TH (through hole) version. Standard TH modules have no On/Off pin fitted. TH modules ordered with device code suffix "1" are negative logic with the On/Off pin fitted. The On/Off pin shall always be fitted on SMT versions.
Vin+
Over Voltage Protection
The output overvoltage protection consists of circuitry that internally clamps the output voltage. If a more accurate output overvoltage protection scheme is required then this should be implemented externally via use of the remote on/off pin.
Vout+
Output Voltage Programming
Ion/off ON/OFF
TRIM
Von/off
Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the TRIM pin and either the Vout+ pin or the Vout- pin. Note: Trim pin is optional on TH module version and always present on SMT versions.

Trim Down - Decrease Output Voltage
Figure 46. Circuit configuration for using Remote On/Off Implementation. To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (Von/off) between the ON/OFF terminal and the VIN(-) terminal. Logic low is 0V Von/off 1.2V. The maximum Ion/off during a logic low is 1mA, the switch should be maintain a logic low level whilst sinking this current. During a logic high, the typical Von/off generated by the module is 5.8V, and the maximum allowable leakage current at Von/off = 5.8V is 50A. If not using the remote on/off feature: For positive logic, leave the ON/OFF pin open. For negative logic, short the ON/OFF pin to VIN(-). By connecting an external resistor between the TRIM pin and Vout+ pin (Radj-down), the output voltage set point decreases (see figure 17). The following equation determines the external resistor value to obtain an output voltage change from Vo, nom to the desired Vo, adj:
(Vo , adj - L) x G Radj - down = - H (Vo , nom - Vo , adj )
Note: Values for G, H, L and K are defined for each module version in the following table 1.

Overcurrent Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. The average output current during hiccup is 10% IO, max.

Feature Descriptions (continued)
Trim Up - Increase Output Voltage
By connecting an external resistor between the TRIM pin and Vout- pin (Radj-up), the output voltage set point increases (see figure 48). The following equation determines the external resistor value to obtain an output voltage change from Vo, nom to the desired Vo, adj:

(4.9 - 2.5) x 5110 Radj - down = - 2050 (5.0 - 4.9) Radj - down = 120,590

The combination of the output voltage adjustment and the output voltage initial tolerance must not exceed the allowable trim range of 90% to 110% of the nominal output voltage as measured between the Vout+ and Vout- pins. The SW/SC power modules have a fixed current-limit set point. Therefore, as the output voltage is adjusted down, the available output power is reduced.

Thermal Considerations
The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The thermal reference point, Tref used in the specifications is shown in Figure 49. For reliable o operation this temperature should not exceed 120 C.

Heat Transfer via Convection
Increased airflow over the module enhances the heat transfer via convection. Derating figures showing the maximum output current that can be delivered by each module versus local ambient temperature (TA) for natural convection and up to 3m/s (600 ft./min) are shown in the respective Characteristics Curves section. Please refer to the Application Note "Thermal Characterization Process For Open-Frame BoardMounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures.

Layout Considerations
The SW/SC power module series are low profile in order to be used in fine pitch system card architectures. As such, component clearance between the bottom of the power module and the mounting board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Also avoid placing via interconnects underneath the power module. For additional layout guide-lines, refer to the FLTR100V10 data sheet.
EMC Considerations

Nozzle Recommendations
The module weight has been kept to a minimum by using open frame construction. Even so, they have a relatively large mass when compared with conventional SMT components. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended nozzle diameter for reliable operation is 5mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 6.5mm. Oblong or oval nozzles up to 11 x 6 mm may also be used within the space available. For further information please contact your local Lineage Power Technical Sales Representative.
The SW/SC family of power modules is available for either Through-Hole (TH) or Surface Mount (SMT) soldering.
Through-Hole Soldering Information
The RoHS-compliant (Z codes) through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHScompliant components. 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 RoHScompliant 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 representative for more details.
Reflow Soldering Information
These power modules are large mass, low thermal resistance devices and typically heat up slower than other SMT components. It is recommended that the customer review data sheets in order to customize the solder reflow profile for each application board assembly. The following instructions must be observed when SMT soldering these units. Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. The surface mountable modules in the SW/SC family use our SMT technology called "Column Pin" (CP) connectors. Figure 53 shows the CP connector before and after reflow soldering onto the end-board assembly.

The CP is constructed from a solid copper pin with an integral solder ball attached, which is composed of tin/lead (Sn63/Pb37) solder for non-Z codes, or Sn/Ag3.8/Cu0.7 (SAC) solder for -Z codes. The CP connector design is able to compensate for large amounts of co-planarity and still ensure a reliable SMT solder joint. Typically, the eutectic solder melts at 183oC (Sn/Pb solder) or 217-218 oC (SAC solder), wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. 21

Storage and Handling
The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40 C, < 90% relative humidity.

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.
