Overview

g n i h tors c t i a Sw egul R STR-W6756 Universal-Input/140 W Off-Line QuasiResonant Flyback Switching Regulator The STR-W6756 is a quasi-resonant regulator specifically designed to satisfy the requirements for increased integration and reliability in switch-mode power supplies.

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

The regulator exhibits only low-level high-frequency EMI noise because of soft switching of the MOSFET close to ground (bottom point).

Key Features

  • Rugged 650 V Avalanche-Rated MOSFET Simplified Surge Absorption No VDSS Derating Required.
  • 0.73 Ω Maximum rDS(on).
  • Two Operational Modes by Automatic Switching: Quasi-Resonant Mode for Normal Operation Burst Mode for Standby Operation or Light Loads.
  • Automatic or Manually Triggered Burst Standby Input Power.
