This reference design converts a universal AC input to an isolated 12-V, 1.5-A output and an isolated 5-V, 0.2-A output. The design achieves a peak efficiency of 92.7%. This reference design features UCC28781-Q1 which is a zero-voltage switching (ZVS) flyback controller to minimize switching losses, UCC5350, a reinforced isolated gate driver to drive the synchronous rectifier MOSFET and TPS629203, a synchronous buck converter with low quiescent current.
