The NCP1399 is a high-performance current-mode controller for half-bridge resonant converters. The controller implements 600 V gate drivers, which simplifies layout and reduces external parts count. The built-in undervoltage input function simplifies the implementation of this controller in all applications. In applications requiring a PFC pre-stage, the NCP1399 has a dedicated output to drive the PFC controller. This feature combined with dedicated skip mode technology further improves the light load efficiency of the entire application. The NCP1399 provides a set of protection features for safe operation in any application. These include: overload protection, overcurrent protection to place hard switching cycles, undervoltage detection, open optocoupler detection, automatic dead time adjustment, overvoltage (OVP) and overtemperature (OTP) protection.
