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.
Features

Low EMI through Variable Frequency Control and AVS Alternating Valley Switching
High-Efficiency through Minimum Voltage Switching
Narrow Frequency Variation Range over Wide Load and Input Voltage Variation
Advanced Burst-Mode Operation for Low Standby Power Consumption
Simple Scheme for Sync Voltage Detection
Pulse-by-Pulse Current Limit
Various Protection functions: Overload Protection OLP, Over-Voltage Protection OVP, Abnormal Over-Current Protection AOCP, Internal Thermal Shutdown TSD with Hysteresis, Output Short Protection OSP
Under-Voltage Lockout UVLO with Hysteresis
Internal Startup Circuit
Internal High-Voltage Sense FET 650V
Built-in Soft-Start 17.5ms
Applications
Power Supply for LCD TV and Monitor, VCR, SVR, STB, and DVD & DVD Recorder
