NCP1218
PWM Controller with
Adjustable Skip Level and
External Latch Input
The NCP1218 represents a new, pin to pin compatible, generation
of the successful 7 ? pin current mode NCP12XX product series. The
controller allows for excellent standby power consumption by use of
its adjustable skip mode and integrated high voltage startup FET.
Internal frequency jittering, ramp compensation, timer ? based fault
detection and a latch input make this controller an excellent
candidate for converters where ruggedness and component cost are
the key constraints.
The Dynamic Self Supply (DSS) drastically simplifies the
transformer design in avoiding the use of an auxiliary winding to
supply the NCP1218. This feature is particularly useful in
applications where the output voltage varies during operation (e.g.
battery chargers). Due to its high voltage technology, the IC can be
directly connected to the high voltage dc rail.
