ONSEMI NCP1236BD65R2G Current Mode Controller
The NCP1236BD65R2G is a high-performance fixed-frequency current mode controller designed for flyback converters and power supplies. Featuring Dynamic Self-Supply (DSS), it simplifies auxiliary supply design and enhances light load efficiency through frequency foldback and skip mode functionality. The device offers adjustable overcurrent and overpower protections, a soft-start feature, and a latch-off input for severe fault conditions like overtemperature. Its advanced high-voltage circuitry ensures reliable startup and brown-out detection, making it ideal for efficient, safe, and low-part-count power supplies in consumer electronics, adapters, and battery chargers.
