APPLICATION NOTE

Requirement 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.

Recommended Circuit

All the PWE_D-6W & PWF_D-6W Series have

been

tested

according

to

the

following

recommended

Single output

(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 of the output filter capacitor must be

proper. If the capacitance is too big, a startup

problem might arise. For every channel of output,

Input Current

When it is used in unregulated power supply, be

sure that the fluctuating range of the power 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), General:
