Overview
The NCP1399ACDR2G is a high-performance current mode controller designed for half-bridge resonant converters, manufactured by onsemi. This controller integrates 600 V gate drivers, which simplifies the layout and reduces the external component count. It features a built-in Brown-Out input function, making it versatile for various applications. Additionally, it includes a dedicated output to drive the PFC controller, enhancing light load efficiency when a PFC front stage is required. The NCP1399ACDR2G is equipped with a suite of protection features to ensure safe operation, including overload protection, overcurrent protection, brown-out detection, open optocoupler detection, automatic dead-time adjustment, overvoltage (OVP), and overtemperature (OTP) protections.
