Quality Control: Learn More
The onsemi NCP1071STCT3G is an offline switching controller designed for flyback topologies. This device integrates a high-voltage planar MOSFET, operating at a fixed 130kHz switching frequency. It features a built-in startup circuit and an internal current-mode controller, simplifying external component count. The NCP1071STCT3G offers robust fault protection, including over-voltage, over-current, over-temperature, and short-circuit protection. With a 700V breakdown voltage and a 68% duty cycle, it is suitable for power supplies up to 14W. This component is housed in a SOT-223 (TO-261) surface-mount package and is supplied on tape and reel. Applications include consumer electronics, home appliances, and industrial power supplies.
