FSQ0565RQ Datasheet Green-mode Power Switch

Manufacturer: onsemi

Overview: FSQ0565RS/RQ — Green-Mode Power Switch for Quasi-Resonant Operation FSQ0565RS/RQ Green-Mode Power Switch for Quasi-Resonant Operation - Low EMI and High.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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 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), LeadingEdge Blanking (LEB), optimized gate driver, internal softstart, temperature-pensated precise current sources for a loop pensation, and self-protection circuitry.

Key Features

  • ! Optimized for Quasi-Resonant Converters (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), Internal.
