Design Reference
1. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.

Dimensions and Recommended Layout
Note:
1. Packing Information please refer to 'Product Packing Information'. Packing bag number: 58210008;
2. Recommended used in more than 5% load, if the load is lower than 5%, then the ripple index of the product may exceed the
specification, but does not affect the reliability of the product;
3. The min. load shall be no lower than 5%, or the output ripple may increase rapidly; If the product is operated under the min. required
load, the product performance cannot be guaranteed to comply with all performance indexes in the Manual, but the reliability of the
product will not be influenced;
4. The max. capacitive load should be tested within the input voltage range and under full load conditions;
5. Unless otherwise specified, data in this datasheet should be tested under the conditions of Ta=25℃, humidity<75% when inputting
nominal voltage and outputting rated load;
6. All index testing methods in this datasheet are based on our Company’s corporate standards;
7. The performance indexes of the product models listed in this datasheet are as above, but some indexes of non-standard model
products will exceed the above-mentioned requirements, and please directly contact our technicians for specific information;
8. We can provide product customization service;
9. Specifications of this product are subject to changes without prior notice.
