Overview

g n i h tors c t i a Sw egul R STR-A6169 Universal-Input/5 W Flyback Switching Regulator The STR-A6169 is a PRC topology (fixed off-time) regulator specifically designed to satisfy the requirements for increased integration and reliability in flyback converters.

It incorporates a primary control and drive circuit with avalanche-rated 800 V power MOSFET.

Covering the power range from below 8 watts for a 230 VAC input, or 5 watts for a universal (85 to 264 VAC) input, this device can be used in a range of applications, from DVD and VCR players to ac adapters for cellular phones and digital cameras.

Key Features

  • Rugged 800 V Avalanche-Rated MOSFET Simplified Surge Absorption No VDSS Derating Required.
  • 19.2 Ω rDS(on).
  • Two Operational Modes by Automatic Switching: PRC Mode for Normal Operation Burst Mode for Stand-By Operation or Light Loads.
  • Built-In Leading Edge Blanking.
  • Low Start-Up Current Start-Up Circuit Disabled in Operation.
  • Low Operating Current (1.5 mA typ).
  • Automatic Burst Stand-By (intermittent operation) Input Power.
