NCP1399ACDR2G Datasheet PDF - ON Semiconductor

The NCP1399 is a high performance current mode controller for half bridge resonant converters. This controller implements 600 V gate drivers, simplifying layout and reducing external component count. The built−in Brown−Out input function eases implementation of the controller in all applications. In applications where a PFC front stage is needed, the NCP1399 features a dedicated output to drive the PFC controller. This feature together with dedicated skip mode technique further improves light load efficiency of the whole application. The NCP1399 provides a suite of protection features allowing safe operation in any application. This includes: overload protection, over−current protection to prevent hard switching cycles, brown−out detection, open optocoupler detection, automatic dead−time adjust, overvoltage (OVP) and overtemperature (OTP) protections.
