Description

This reference design provides 32V at 100W from a universal AC input. An auxiliary 14V is also provided and can support loads up to 250mA. The UCC28600 quasi-resonant flyback controller allows this design to achieve efficiencies over 86% with a 120VAC input and over 88% with a 230VAC input, yet minimizes light-load losses.
