Description

This reference design is a 2.2-W multi-output flybuck design for isolated gate-drive bias supplies. The supply is designed to accept an input from 24-V systems. This design uses the LM36520 synchronous buck converter to generate four isolated outputs. Primary-side regulation maintains each of the four 17-V outputs within ±10%.
