3DAW_S & 3DAW_D Series

3W - Dual/Single Output - Wide Input - Isolated & Regulated

DC-DC Converter

Typical application

EMC solution-recommended circuit

Requirement on output load

To ensure that the module can work efficiently and reliably, its output

min. load shall be no lower than 5% of the rated load when using, or

the output ripple may increase rapidly. Ensure that the product wor-

king load must be higher than 5% of the rated load.

Recommended Circuit

All the DC/DC converters of this series are tested according to the re-

commended circuit (see Fig. 1) before delivery.

If it is required to further reduce input and output ripple, properly in-

crease the input & output of additional capacitors Cin and Cout or

select capacitors of low equivalent impedance provided that the capa-

citance is no larger than the max. capacitive load of the product.
