Power chip

The NCP13992 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 that require a PFC pre-stage, the NCP13992 has a dedicated output to drive the PFC controller. This feature, combined with dedicated noise-free skip mode technology, further improves the light load efficiency of the entire application. The NCP13992 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.
