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
isolated from the input power supply in a
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 range4:1);
2) Where isolation is necessary between input
and output (isolation1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

* 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.

OUTLINE DIMENSIONS & FOOTPRINT DETAILS
Recommended Circuit
All the PWA_(M)D-3W & PWB_(M)D-3W Series
have been tested according to the following
recommended testing circuit before leaving
factory. This series should be tested under load
(see Figure 1).

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.
