Design Considerations

Input Source Impedance

The power module should be connected to a low

ac-impedance input source. Highly inductive source

impedances can affect the stability of the power mod-

ule. For the test configuration in Figure 7, a 33 µF

electrolytic capacitor (ESR < 0.7  at 100 kHz) mounted

close to the power module helps ensure stability of the

unit. Consult the factory for further application

guidelines.

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. To 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. GE 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

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. 60950-1-03,

EN60950-1 and VDE 0805:2001-12.

For end products connected to –48V dc, or –60Vdc

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.

GE Data Sheet

QPW025A0F41/QPW025A0F41-H DC-DC Power Module

36-75Vdc Input; 3.3Vdc Output Voltage; 25A Output Current

 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.

For all input sources, other than DC MAINS, where the

input voltage is between 60 and 75V dc (Classified as

TNV-2 in Europe), the following must be meet, if the

converter’s output is to be evaluated for SELV:

 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.

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 6A fast-acting (or time-delay) fuse in the

unearthed lead.

Feature Descriptions

Remote On/Off

Two remote On/Off logic options are available. Positive

logic remote On/Off turns the module ON during a

logic-high voltage on the remote On/Off pin, and turns

the module OFF during a logic-low. Negative logic

remote On/Off turns the module OFF during a logic-

high and turns the module ON during logic-low.

Negative logic is specified by suffix “1” at the end of the

device code.

To turn the power module on and off, the user must

supply a switch to control the voltage between the

ON/OFF pin and the VIN(–) terminal (Von/Off). The switch

may be an open collector or equivalent (see Figure 10).

A logic-low is Von/off = 0 V to 1.2V. 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 is 50 µA. If not using the

remote on/off feature, do one of the following:

For positive logic, leave the ON/OFF pin open.

For negative logic, short the ON/OFF pin to VIN(–).

Overcurrent Protection

To provide protection in a fault (output overload) condi-

tion, the module is equipped with internal current-limit-

ing circuitry, and can endure current limiting

continuously. At the instance of current-limit inception,

the output current begins to tail-out. When an

overcurrent condition exists beyond a few seconds, the

module enters a “hiccup” mode of operation, whereby

it shuts down and automatically attempts to restart..

While the fault condition exists, the module will remain

in this hiccup mode, and can remain in this mode until

the fault is cleared. The unit operates normally once

the output current is reduced back into its specified

range.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout

limit, the module operation is disabled. The module will

begin to operate at an input voltage between the

undervoltage lockout limit and the minimum operating

input voltage.

Overtemperature Protection

To provide over temperature protection in a fault

condition, the unit relies upon the thermal protection

feature of the controller IC. The unit will shut down if

the thermal reference point Tref, exceeds the specified

maximum temperature threshold, but the thermal

shutdown is not intended as a guarantee that the unit

will survive temperatures beyond its rating. The

module will automatically restart after it cools down.

36-75Vdc Input; 3.3Vdc Output Voltage; 25A Output Current

Feature Descriptions (continued)

Over Voltage Protection

The output overvoltage protection clamp consists of

control circuitry, independent of the primary regulation

loop, which monitors the voltage on the output

terminals. This control loop has a higher voltage set

point than the primary loop (See the overvoltage clamp

values in the Feature Specifications). In a fault

condition, the overvoltage clamp ensures that the

output voltage does not exceed Vo, clamp(max). This

provides a redundant voltage-control that reduces the

risk of output overvoltage.

Remote sense

Remote sense minimizes the effects of distribution

losses by regulating the voltage at the remote-sense

connections (See Figure 11). The voltage between the

remote-sense pins and the output terminals must not

exceed the output voltage sense range given in the

Feature Specifications table:

[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 setpoint

adjustment (trim) (see Figure 11). 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.

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 (Maximum rated power = Vo,set x Io,max).

Output Voltage Programming

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. 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 12 shows the

circuit configuration using an external resistor. The trim

resistor should be positioned close to the module. If the

Thermal Considerations

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-dissipation components are mounted on the

topside 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. Peak temperature

can occur at any to these positions indicated in the

following figure 14.

Please refer to the Application Note “Thermal

Characterization Process For Open-Frame Board-

thermal aspects including maximum device

temperatures.

Heat Transfer via Convection

Increased airflow over the module enhances the heat

transfer via convection. Thermal derating curves

showing the maximum output current that can be

delivered by the module versus local ambient

temperature (TA) for natural convection, 0.5m/s (100

ft./min) and 1.0 m/s (200 ft./min) are shown in Fig. 15

for the bare module and in Fig. 16 for the module with

baseplate.

Note that the natural convection condition was

measured at 0.05m/s to 0.1m/s (10ft./min. to

20ft./min.); however, systems in which these power

modules may be used typically generate natural

convection airflow rates of 0.3m/s (60 ft./min.) due to

other heat dissipating components in the system.
