Product Introduction

Overview

The NCP43080DDR2G is a synchronous rectifier controller produced by onsemi, designed for switch mode power supplies. It is packaged in an 8-pin SOIC and is optimized for high efficiency designs in flyback and quasi-resonant flyback topologies. The controller features externally adjustable minimum off-time and on-time blanking periods, allowing flexibility to drive various MOSFET package types and PCB layouts. It ensures reliable and noiseless operation of the synchronous rectifier (SR) system through its self-synchronization feature and utilizes Kelvin connection to the MOSFET for high efficiency at full load. Additionally, it includes light load detection architecture for high efficiency at light loads.
