Design Reference
1. Typical application
All the DC/DC converters of this series are tested before delivery using the recommended circuit shown in Fig. 2.
Input and/or output ripple can be further reduced by appropriately increasing the input & output capacitor values Cin and Cout and/or by
selecting capacitors with a low ESR (equivalent series resistance). Also make sure that the capacitance is not exceeding the specified max.
capacitive load value of the product.
