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 that is well suited  
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 Start-up Circuit  
„ Internal High-Voltage Sense FET (650V)  
„ Built-in Soft-Start (15ms)  
Applications  
„ Power Supply for LCD TV and Monitor, VCR, SVR,  
STB, and DVD & DVD Recorder  
„ Adapter
