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 builtin BrownOut 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, overcurrent protection to prevent hard switching  
cycles, brownout detection, line brownout, line OVP, X2 cap  
discharge, open optocoupler detection, automatic deadtime adjust,  
overvoltage (OVP) and overtemperature (OTP) protections.
