The onsemi NCP1051ST100T3G is an offline switching controller designed for flyback topologies. This device integrates a high-voltage MOSFET, enabling efficient power conversion up to 40W. Operating at a fixed switching frequency of 100kHz, it features a 77% duty cycle and a 700V breakdown voltage. Built-in fault protection mechanisms include current limiting, open loop, overload, and over-temperature protection. The device operates within a supply voltage range of 7.5V to 10V, with a startup voltage of 8.5V. The NCP1051ST100T3G is packaged in a SOT-223 (TO-261) surface-mount package and is supplied on tape and reel. Its isolated output and robust protection features make it suitable for applications in consumer electronics and industrial power supplies.
