Description The MW005A, B, C, BK, and CL Power Modules are dc-dc converters that operate over a wide input-voltage range of 36 Vdc to 75 Vdc and provide precisely regulated dc outputs. The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings of 5 W at typical full-load efficiencies of 82% (80% for the MW005A). The modules are encapsulated in nonconductive cases that mount on printed-circuit boards. In a natural convection environment, the modules are rated to full load at 70 °C with no heat sinking or external filtering. The modules can be used up to 85þ°C with derated output power (4.5þW with an external input capacitor; 3.5þW with no external capacitor).

Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Fusing Considerations CAUTION: This power module is not internally fused. An input line fuse must always be used. This encapsulated 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 5 A in series with the input (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.

Figure 26. MW005A, B, C Output Voltage and Efficiency Measurement Test Setup
An internal aluminum electrolytic input capacitor is used for filtering; therefore, input ripple increases as temperature decreases. There is approximately two times more ripple at 0 °C than at 25 °C and eight times more ripple at –40 °C than at 25 °C. The power module functions properly down to –40 °C with no additional filtering. If lower ripple comparable to that at 25 °C is needed at low temperatures, an external capacitor across the input with an impedance of 0.5 Ω at 100 kHz over the desired temperature range is recommended. See Figure 24 for the test setup.
Input or Output Voltage Reversal CAUTION: Applying a reverse voltage across the module input or output can damage the module.

Safety Considerations
Output Overvoltage Protection
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 1950, CSA C22.2 No. 950-95, and VDE 0805 (EN60950, IEC950).
The output overvoltage clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop (see Feature Specifications table). This provides a redundant voltage control that reduces the risk of output overvoltage.
■
The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains; and
■
One VI pin and one VO pin are to be grounded or both the input and output pins are to be kept floating; and
■
The input pins of the module are not operator accessible; and
■
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.
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. The input to these units is to be provided with a maximum 5 A normal-blow fuse in the ungrounded lead.
Thermal Considerations To maintain the full power rating at ambient temperatures above 70 °C (TA > 70 °C), add an external capacitor across the input close to the power module input leads. Use an 80 V capacitor with a minimum ripple current rating of 160 mArms and maximum impedance of 1.0 Ω at 105 °C and 100 kHz. Otherwise, derate the output power as shown in Figure 28. 5.0 4.5 OUTPUT POWER, PO (W)
If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75 Vdc), for the module's output to be considered meeting the requirements of safety extra-low voltage (SELV), all of the following must be true:

Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. If the output voltage is pulled very low during a severe fault, the current-limit circuit can exhibit either foldback or tailout characteristics (output current decrease or increase). The unit operates normally once the output current is brought back into its specified range.
