FSQ0565R datasheet

 

Description :

A Quasi-Resonant Converter (QRC) generally shows lower EMI and higher power conversion effiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ-series is an integrated Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for quasi-resonant operation and Alternating Valley Switching (AVS).
