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). 

Pinout



Features

1. Optimized for Quasi-Resonant Converters (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

5. Advanced Burst-Mode Operation for Low Standby Power Consumption

6. Simple Scheme for Sync Voltage Detection

7. Pulse-by-Pulse Current Limit
