The LM5157EVM-FLY evaluation module showcases the features and performance of the LM5157 as a flyback converter to produce multiple output voltage rails for typical applications of the 3phase inverter gate driver bias supplies. The standard configuration is designed to provide a regulated output of 10-V at 250 mA from an input of 8-V to 16-V, and three isolated 20-V rails at 75 mA, 75 mA and 150 mA respectively. The switching is at 250 kHz.
