Green-Mode Fairchild Power Switch (FPSô) for Quasi-Resonant Operation - Low EMI and High Efficiency
Share:
Manufacturer

Description

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
Optimized for Quasi-Resonant Converter (QRC)
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
Adapter
