FSQ0765RS  
Green-Mode Fairchild Power Switch (FPS™) for  
Quasi-Resonant Operation - Low EMI and High Efficiency  
Features  
Description  
! Optimized for Quasi-Resonant Converter (QRC)  
! Low EMI through Variable Frequency Control and AVS  
A Quasi-Resonant Converter (QRC) generally shows  
lower EMI and higher power conversion efficiency than a  
(Alternating Valley Switching)  
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). The  
PWM controller includes an integrated fixed-frequency  
oscillator, Under-Voltage Lockout (UVLO), Leading-  
Edge Blanking (LEB), optimized gate driver, internal soft-  
start, temperature-compensated precise current sources  
for a loop compensation, and self-protection circuitry.  
Compared with a discrete MOSFET and PWM controller  
solution, the FSQ-series can reduce total cost,  
component count, size, and weight; while simultaneously  
increasing efficiency, productivity, and system reliability.  
This device provides a basic platform for cost-effective  
designs of quasi-resonant switching flyback converters.  
! 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  
! Adapter
