Datasheet 28103.44-6b The STR-A6259H is a 100 kHz PWM topology (with ±5% frequency jittering for minimum EMI) regulator specifically designed to satisfy the requirements for increased integration and reliability Package DIP-8 in flyback converters. It incorporates a primary control and drive circuit with an avalanche-rated power MOSFET. Covering the power range from below 17 watts for a 230 VAC input, or to 13 watts for a universal (85 to 264 VAC) Approximate Scale 1:1 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 a...
