FSQ321 - Green Mode Fairchild Power Switch

This page provides the datasheet information for the FSQ321, a member of the FSQ0165 Green Mode Fairchild Power Switch family.

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.
