MARKING DIAGRAM
The NCP13992 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 NCP13992 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
NCP13992 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,
over−voltage (OVP) and over−temperature (OTP) protections.
