FSCQ0765RTYDTU

FAIRCHILD SEMICONDUCTOR  FSCQ0765RTYDTU  芯片, 电源开关 SMPS 节能模式

The is a 650V Integrated Power Switch for 85W offline flyback converters. A Quasi-Resonant Converter QRC typically shows lower EMI and higher power conversion efficiency compared to a conventional hard-switched converter with a fixed switching frequency. Therefore, a QRC is well suited for noise-sensitive applications, such as colour TV and audio. Each product in the FSCQ series contains an integrated Pulse Width Modulation PWM controller and a SenseFET. This series is specifically designed for quasi-resonant off-line Switch Mode Power Supplies SMPS with minimal external components. The PWM controller includes an integrated fixed frequency oscillator, under-voltage lockout, leading-edge blanking LEB, optimized gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation and self-protection circuitry.
