Universal-Input 20 W 67 KHz Flyback Switching Regulators | STR-A6252MD

The STR-A6252MD is a 67 kHz PWM topology (with 5% frequency jittering for minimum EMI) Regulator specifically designed to satisfy the requirements for increased integration and reliability in flyback converters. It incorporates a primary control and drive circuit with an avalanche-rated Power MOSFET This is a higher-frequency version of the STR-A6252D.
Covering the power range from below 24 watts for a 230 VAC input, or to 20 watts for a universal (85 to 264 VAC) input, this device CAN be used in a wide range of applications, from DVD players and VCR player/recorders to ac adapters for cellular phones and digital cameras. An auto-burst standby function reduces power consumption at light load, while multiple protections, including the avalanche-energy guaranteed MOSFET provide high reliability of system design.
