15-W multi-output off-line flyback reference design

This reference design takes a universal Vac input and creates three isolated 15-Vdc outputs. The main output can be loaded up to 1-A and achieves over 86% efficiency. The other isolated 15-V outputs can be loaded to 50-mA. These outputs have linear regulators to keep the voltages within 1 (...)
