High Performance Current

Mode Resonant Controller

with Integrated High-

Voltage Drivers

www.onsemi.com

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.
