Recommended Circuit

Although these converters could work without external capacitor, it is recommended that with external output capacitor Cout which could reduce output ripple & noise under 30mVp-p.        

The followings are the recommended circuit and values.                                    

Recommended Circuit for Reduced Ripple

Use the low ESR Cout capacitors and

inductor Lin to reduce output ripple and

input inrush current.
