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.
An auto-standby function reduces power consumption at light load, while multiple protections, including the avalanche-energy guaranteed MOSFET, provide high reliability of system design.
Devices with an increased output power rating are the STR-A6151 and S...
