GENERAL DESCRIPTION
DP4110B 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.
DP4110B is built-in HV supplies for VDD capacitor,that can eliminate the aux-winding of VDD supply for cost saving.
DP4110B integrated protections of Under Voltage Lockout(UVLO),VDD clamper
