FSQ0265 Datasheet Green Mode Fairchild Power Switch

Manufacturer: Fairchild (now onsemi)

Overview: FSQ0365/0265/0165/321 — Green Mode Fairchild Power Switch (FPS™) for Valley Switching Converter August 2011 FSQ0365, FSQ0265, FSQ0165, FSQ321 Green Mode Fairchild Power Switch (FPS™) for Valley Switching Converter – Low.

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

General 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.

The FSQ-series is an integrated Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for valley switching operation with minimal external ponents.

The PWM controller includes an integrated fixed-frequency oscillator, under-voltage lockout, Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, temperature-pensated precise current sources for loop pensation, and self-protection circuitry.

Key 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.
