The onsemi NCP1050ST100T3G is an offline switching regulator designed for flyback topologies. This device integrates a 700V power switch and a voltage mode controller, enabling efficient power conversion at a fixed switching frequency of 100kHz. It features internal startup circuitry requiring 8.5V for activation and operates within a Vcc range of 7.5V to 10V. The NCP1050ST100T3G offers robust fault protection, including current limiting, open loop, overload, and over-temperature protection, making it suitable for demanding applications. Its high 77% duty cycle capability and 40W power output are advantageous for power supplies in consumer electronics, industrial automation, and lighting control systems. Packaged in a SOT-223 (TO-261) surface-mount configuration and supplied on tape and reel, this component facilitates automated assembly. The internal switch configuration and isolated output are key design elements for reliable offline power conversion.
