Green Mode Fairchild Power Switch (FPS™) for  
Valley Switching Converter - Low EMI and High Efficiency  
Features  
Description  
„ Optimized for Valley Switching (VSC)  
A Valley Switching Converter generally shows lower EMI  
and higher power conversion efficiency than  
a
„ Low EMI through Variable Frequency Control and  
conventional hard-switched converter with fixed  
a
Inherent Frequency Modulation  
switching frequency. The FSQ-series is an integrated  
Pulse-Width Modulation (PWM) controller and  
SenseFET specifically designed for valley switching  
operation 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.  
„ 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  
„ Pulse-by-Pulse Current Limit  
„ Various Protection Functions: Overload Protection  
(OLP), Over-Voltage Protection (OVP), Abnormal  
Over-Current Protection (AOCP), Internal Thermal  
Shutdown (TSD)  
Compared with discrete MOSFET and PWM controller  
solutions, the FSQ-series reduces 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 valley switching fly-back converters.  
„ Under-Voltage Lockout (UVLO) with Hysteresis  
„ Internal Start-up Circuit  
„ Internal High-Voltage SenseFET (650V)  
„ Built-in Soft-Start (15ms)  
Applications  
„ Power Supply for DVP Player and DVD Recorder,  
Set-Top Box  
„ Adapter  
„ Auxiliary Power Supply for PC, LCD TV, and PDP TV  
Related Application Notes
