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

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.
