The onsemi NCP1399BADR2G is a highly integrated controller for high-efficiency half-bridge LLC resonant converters. This device operates across a switching frequency range of 20kHz to 750kHz, supporting a 50% duty cycle. It features a robust fault protection suite including current limiting, open loop, overload, over-temperature, over-voltage, and short circuit protection. Designed for isolated power supplies, the NCP1399 series controller requires an external power stage. Key operating parameters include a start-up voltage of 15.8V and a supply voltage range of 9.5V to 20V. The NCP1399BADR2G is supplied in a 16-SOIC package suitable for surface mounting and is delivered on tape and reel. This component is commonly utilized in consumer electronics, industrial power supplies, and LED lighting applications where efficient power conversion is critical.
