NCP1399ACDR2G NCP1399AC high-performance current mode resonant controller with integrated high-voltage drivers
NCP1399ACDR2G / NCP1399AC of the NCP1399 series 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. In applications where a PFC front stage is needed, the NCP1399 features a dedicated output to drive the PFC controller. This feature together with the dedicated skip mode technique further improves the light load efficiency of the whole application.
The NCP1399 provides a suite of protection features allowing the safe operation of 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) protection. Available in SOIC-16 NB package.
