NCP1399AC

NCP1399AA, NCP1399BA, NCP1399AC, NCP1399AF High Performance Current Mode Resonant Controller with Integrated HighVoltage Drivers 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. Features High−Frequency Operation from 20 kHz up to 750 kHz Current Mode Control Scheme Automatic Dead−time with Maximum Dead−time Clamp Dedicated Startup Sequence for Fast Resonant Tank Stabilization Skip Mode Operation for Improved Light Load Efficiency Off−mode Operation for Extremely Low No−load Consumption Latched or Auto−Recovery Overload Protection Latched or Auto−Recovery Output Short Circuit Protection Latched Input for Severe Fault Conditions, e.g. OVP or OTP Out of Reson...
