Quality Control: Learn More
The onsemi NCP1051ST136T3 is an offline switching regulator designed for flyback topologies, operating at a 136kHz switching frequency within a SOT-223 (TO-261) package. This component features an integrated 700V power switch and is suitable for applications requiring up to 40W output power. Key internal fault protection mechanisms include current limiting, open loop, overload, and over-temperature protection. The device initiates operation at 8.5V, drawing power from a supply voltage range of 7.5V to 10V, and offers a maximum duty cycle of 77%. Its isolated output and robust construction make it ideal for power supplies in consumer electronics, industrial automation, and lighting applications. The NCP1051ST136T3 is supplied in Tape & Reel packaging.
