APPLICATIONS

The PWA_(M)PD-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 range: 4:1);

2) Where isolation is necessary between

input and output

(isolation =1500VDC);

3) Where the regulation of the output

voltage and the output ripple noise are

demanded.

supply and the rippled voltage do not exceed the

module standard. Input current of power supply

should afford the startup current of this kind of

DC/DC module. (See figure 2)

External Capacitor

Although this series of DC/DC converter can

work without external capacitor, in order to keep

an optimum performance, however, it needs

external capacitor. (See Table 1)

Requirement on Output Load

To ensure this module operate efficiently and

reliably, a minimum load is specified for this kind

of DC/DC converter in addition to a maximum

load (namely full load). During operation, make

sure the specified range of input voltage is not

exceeded, the minimum out put load is not less

than 10% Of the full load, and that this product

should never be operated under no

1011

load!!! If the actual load is less below the

specified minimum load, the output ripple of this

type of DC/DC converter will increase drastically

and at the same time efficiency & reliability of

the circuit will decrease deeply .If the actual

output power from the load in your circuit is very

small, please connect a resistor with proper

resistance at the output end to in parallel to

increase the load, or use our company’s other

products with a lower rated output power.

APPLICATION NOTE

Recommended Circuit

All the PWA_(M)PD-3W Series have been tested according to the following recommended testing circuit

before leaving factory. This series should be tested under load. Never be tested under no 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.(See table 1).If you want to use

the products in high EMI, please choose our metal packaged products.
