NCP13994

MARKING DIAGRAM

The NCP13994 is a high performance current mode controller for

half bridge resonant converters. This controller implements

700 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 NCP13994 features a dedicated

output to drive the PFC controller. This feature together with quiet

skip mode technique further improves light load efficiency of the

whole application. The NCP13994 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, line brown−out, line OVP, X2 cap

discharge, open optocoupler detection, automatic dead−time adjust,

over−voltage (OVP) and over−temperature (OTP) protections.
