General Description

KP411X is a family of secondary side synchronous rectifier, that replaced Schottky diodes by combined with an ultra low on-state resistance power MOSFET for high-efficiency flyback converters.

It supports High-Side and Low-Side in DCM and Quasi-Resonant Topologies.

KP411X is built-in HV supplies for VDD capacitor, that can eliminate the aux-winding of VDD supply for cost saving.
