FSQ510 Datasheet Green Mode Fairchild Power Switch

Manufacturer: Fairchild (now onsemi)

General 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 FSQ510(H) is an integrated Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for quasi-resonant offline Switch Mode Power Supplies (SMPS) with minimal external components.

The PWM controller includes an integrated fixed-frequency oscillator, Under-Voltage Lockout (UVLO), Leading Edge Blanking (LEB), optimized gate driver, internal soft start, temperaturecompensated precise current sources for loop compensation, and self-protection circuitry.
