NCP1399 Series
High Performance Current
Mode Resonant Controller
with Integrated High-
Voltage 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
builtin BrownOut 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, overcurrent
protection to prevent hard switching cycles, brownout detection, open
optocoupler detection, automatic deadtime adjust, overvoltage (OVP)
and overtemperature (OTP) protections.
