KP4126X series
KP4126X High-performance, secondary-side synchronous rectifier power switch The KP4126X is a high-performance synchronous rectifier power switch designed to replace the secondary-side Schottky diode in flyback converters. It integrates an ultra-low on-resistance power MOSFET to improve system efficiency. The KP4126X supports High Side and Low Side configurations, and supports both Discontinuous Conduction Mode (DCM) and Quasi-Resonant Mode (QR). The KP4126X integrates a VDD high-voltage power supply module, eliminating the need for a VDD auxiliary winding, thus reducing system cost. For 12V systems in Low Side configuration, a Vo LDO power supply method is added to reduce power consumption. The KP4126X integrates VDD undervoltage protection and VDD voltage clamping functions.
