APPLICATIONS

The PWA_(M)D-3W & PWB_(M)D-3W Series

are specially designed for applications where a

wide range input voltage power supplies are

18-72

600

250

isolated from the input power supply in

200

distributed power supply system on a circuit

board. These products apply to:

1) Where the voltage of the input power supply

is wide range (voltage range≤ 4:1);

2) Where isolation is necessary between input

and output (isolation≤1500VDC);

* Input voltage over it may cause permanent damage to the device.

Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.

Operation under 10% load will not damage the converter; However, they may not meet all specification

listed.

3) Where the regulation of the output voltage

and the output ripple noise are demanded.

If you want to further decrease the input/output

ripple, you can increase capacitance properly or

choose capacitors with low ESR. However, the

capacitance should not be too high, or may cause

start-up problem. If you want to use the products in

high EMI, please choose our metal packaged

products (PWA_MD-3W&PWB_MD-3W).

APPLICATION NOTE

Requirement on output load

In order to ensure the product operate efficiently and reliably, in addition to a max load

(namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure the

specified range of input voltage is not exceeded, the minimum output load no less than 10%

load. If the actual load is less than the specified minimum load, the output ripple may increase

sharply while its efficiency and reliability will reduce greatly. If the actual output power is very

small, please add an appropriate resistor as extra loading, or contact our company for other

lower output power products.
