FSQ211 - Green Mode Fairchild Power Switch

Description

The FSQ211 consists of an integrated Pulse Width Modulator (PWM) and SenseFET, specifically designed for high-performance, off-line Switch Mode Power Supplies (SMPS) with minimal external components.

Features

  • Internal Avalanche-Rugged SenseFET.
  • Precision Fixed Operating Frequency (67KHz).
  • Burst-Mode Operation.
  • Internal Start-up Circuit.
  • Pulse-by-Pulse Current Limiting.
  • Overload Protection (OLP).
  • Internal Thermal Shutdown Function (TSD).
  • Auto-Restart Mode.
  • Under-Voltage Lockout (UVLO) with Hysteresis.
  • Built-in Soft-Start.
  • Secondary-Side Regulation.
