FSQ0565RQ - Green-Mode Power Switch

Download the FSQ0565RQ datasheet PDF. This datasheet also covers the FSQ0565RS variant, as both devices belong to the same green-mode power switch family and are provided as variant models within a single manufacturer datasheet.

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.

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.
