onsemi Integrated Circuits (ICs) - PMIC - AC DC Converters, Offline Switchers NCP1399AHDR2G

The NCP1399AHDR2G is a high-performance current mode controller designed for half-bridge resonant converters, featuring integrated 600 V gate drivers that simplify layout and reduce the external component count. It operates at frequencies ranging from 20 kHz to 750 kHz and includes a dedicated output for driving a power factor correction (PFC) controller, enhancing efficiency in applications requiring a PFC front stage. This controller incorporates several protection features, including overload protection, over-current protection, brown-out detection, and over-voltage and over-temperature protections, ensuring safe operation across various applications. It also supports skip mode operation for improved light load efficiency and off-mode operation for extremely low no-load consumption. Typical applications for the NCP1399AHDR2G include adapters, offline battery chargers, flat panel display power converters, and power supplies for computing and industrial or medical sources. The device is packaged in a 16-pin SOIC format and is Pb-free, making it suitable for environmentally conscious designs.
