Overview
KP4110/KP4111 Secondary Side Synchronous Rectifier (SR) FEATURES  Secondary Side Synchronous Rectifier(SR) for Flyback converters  Supports High-Side and Low-Side in DCM and Quasi-Resonant Topologies  <300uA Low Quiescent Current  Built-in HV Supplies without Aux-Winding for VDD supply  Integrated with 45V Power MOSFET  Built-in Protections:  VDD UVLO  VDD Clamper by >5mA sink current  Available with SOP-8 Package APPLICATIONS  Flyback converters  Chargers TYPICAL APPLICATION CIRCUIT High Side SR 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.
KP411X integrates protections of Under Voltage Lockout (UVLO...
