Description
The EQD075 series DC-DC converters are a new generation of open-frame DC/DC power modules designed to support a 3:1 input voltage range, that allows operation in both 24V or 48V nominal input voltage systems, thus eliminating the need for separate power modules for each input voltage range. These single output DC-DC converters operate over an input voltage range of 18 to 60 Vdc. The series is also designed to provide a wide output voltage set/trim range of 3.0 to 5.5Vdc, with output current up to 20A at 3.3Vdc or 15A at 5.0Vdc in an industry standard eighth brick package. The output is isolated from the input, allowing versatile polarity configurations and grounding connections. Built in filtering for both input and output minimizes the need for external filtering.

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 a 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 very fast acting surface mount fuse with a maximum rating of 6.3 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 sheet for further information.

Design Considerations
Input Filtering The power module should be connected to a low acimpedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 17, a 220F electrolytic capacitor (ESR<0.1 at 100 kHz), mounted close to the power module helps ensure the stability of the unit. Consult your sales representative for further applications guidelines.
NOTE: Measure input reflected ripple current with a simulated source inductance (L TEST ) of 12H. Capacitor C S 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., UL60950-1, CSA C22.2 No. 60950-103, EN60950-1 and VDE 0805:2001-12. These converters have been evaluated to the spacing requirements for Basic insulation, per the above safety standards; and 1500 Vdc is applied from Vin to Vout to 100% of outgoing production. For end products connected to -48V dc nominal DC MAINS (i.e. central office dc battery plant), no further fault testing is required. For all input voltages, other than DC MAINS, where the input voltage is less than 60V dc, if the input meets all of the requirements for SELV, then: The output may be considered SELV. Output voltages will remain within 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. 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, or tested to the UL60950 A.2 for reduced thickness. The input to these units is to be provided with a maximum 6.3 A very fast-acting surface mount fuse in the unearthed lead.

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. If the auto-restart option (4) is ordered, the module will automatically restart upon cool-down to a safe temperature.
Feature Descriptions
Remote On/Off
The EQD075 series power modules have primary referenced remote On/Off. The remote on/off is open collector compatible with the signal common referenced to the negative input. The standard remote on/off negative logic is such that a unit operates (ON) when the remote on/off signal is low or short circuit to minus VIN. A module will be OFF when the remote on/off pin is open circuit or when the remote on/off signal is high. The optional positive logic remote on/off is such that a unit operates (ON) when the remote on/off signal is high or open-circuit. A unit will be OFF when the remote on/off signal is low or short-circuited to minus VIN.
Over Voltage Protection
The output over voltage protection scheme of the modules has an independent over voltage loop to prevent single point of failure. This protection feature latches in the event of over voltage across the output. Cycling the on/off pin or input voltage resets the latching protection feature. If the auto-restart option (4) is ordered, the module will automatically restart upon an internally programmed time elapsing.

Remote sense

Ion/off ON/OFF

COM
The EQD075 series power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage at the Remote Sense pin (See Figure 21). The voltage between the Sense pin and Vo pin must not exceed 0.5V. The opened sense line resistor value should be selected in range of 30 ohm - 100 ohm that eases use of external parallel load share controller. The amount of power delivered by the module is defined as the output voltage multiplied by the output current (Vo x Io). When using Remote Sense, the output voltage of the module can increase, which, if the same output is maintained, increases the power output from the module. Make sure that the maximum output power of the module remains at or below the maximum rated power. When the Remote Sense feature is not being used, connect the Remote Sense pins to the output pins of the module.

Figure 20. Circuit configuration for using Remote On/Off Implementation.
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 a hiccup mode. If the unit is not configured with auto-restart, then it will latch off following the over current condition. 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. If the unit is configured with the auto-restart option (4), it will remain in the hiccup mode as long as the overcurrent condition exists; it operates normally, once the output current is brought back into its specified range.

Feature Descriptions (continued)
Output Voltage Programming
The output voltage is adjustable between 3.0 to 5.5V (A version). A resistor placed between the Trim pin and Sense (+) increases the output voltage and a resistor placed between the Trim pin and Sense (-) decreases the output voltage. Figure 22 shows the circuit configuration using an external resistor. The trim resistor should be positioned close to the module. If the trim pin is not used then the pin shall be left open. If no trim resistor is connected, for the A version, the output voltage will be 5V. The following equations determine the required external resistor value to obtain a percentage output voltage change of %. To decrease output voltage set point:
Thermal Considerations
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 is based on physical measurements taken in a wind tunnel. The test set-up is shown in Figure 23.

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 absolute increase in output voltage, due to simultaneous remote sense and trim increases, shall not exceed the larger of the specified individual remote sense or trim maximum limits shown in the Features Specifications table.

Through-Hole Lead-Free Soldering Information
The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant 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 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 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. For guidance on appropriate soldering, cleaning and drying procedures, refer to Lineage Power Board Mounted Power Modules: Soldering and Cleaning Application Note.
