Note:
1. Recommend to use module with more than 5% load, if not, the ripple of the
product may exceeds the specification, but does not affect the reliability of the
product;
3. The recommended unbalance degree of the dual output module load is ≤ 5%;
if the degree exceeds 5%, than the product performance cannot be gua-
ranteed to comply with all parameters in the datasheet. Please contact our
technicians directly for specific information;

Typical application
All the 20DAW4_1.5 Series are tested according to the recommended
circuit (see Fig. 1) before delivery.
External capacitor table
If a further decrease of the input and output ripple is required, properly
increase the input & output of additional capacitors Cin and Cout
or select capacitors of low equivalent impedance, and ensure the capa-
citance should be lower than the max. capacitive load of the
product.
