Part Number : FSQ0765RS
Function : Green-Mode Fairchild Power Switch / Internal High-Voltage Sense FET (650 V)
Package : TO-220F-6L Type
Maker : Fairchild Semiconductor
Pinouts : 
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). 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.
Features
1. Optimized for Quasi-Resonant Converter (QRC)
2. Low EMI through Variable Frequency Control and AVS (Alternating Valley Switching)
3. High Efficiency through Minimum Voltage Switching
4. Narrow Frequency Variation Range over Wide Load and Input Voltage Variation
