FSQ321 - Green Mode Fairchild Power Switch

Download the FSQ321 datasheet PDF. This datasheet also covers the FSQ0165 variant, as both devices belong to the same green mode fairchild power switch family and are provided as variant models within a single manufacturer datasheet.

Description

A Valley Switching Converter generally shows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency.

Features

  • Optimized for Valley Switching Converter (VSC).
  • Low EMI through Variable Frequency Control and Inherent Frequency Modulation.
  • 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.
  • Pulse-by-Pulse Current Limit.
  • Protection Functions: Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal OverCurrent Protection (AO.
