FSQ0765RQWDTU

FAIRCHILD SEMICONDUCTOR  FSQ0765RQWDTU  电源负载开关, 用于准共振操作, 1路输出, 20V, 3.5A, TO-220-6

Description

A Quasi-Resonant Converter QRC generally shows lower EMI and higher power conversion efficiency 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.
