NCP1271
Soft-Skip t Mode Standby
PWM Controller with
Adjustable Skip Level and
External Latch
The NCP1271 represents a new, pin to pin compatible, generation
http://onsemi.com
of the successful 7 ? pin current mode NCP12XX product series. The
controller allows for excellent stand by power consumption by use of
its adjustable Soft ? Skip mode and integrated high voltage startup
FET. This proprietary Soft ? Skip also dramatically reduces the risk of
acoustic noise. This allows the use of inexpensive transformers and
capacitors in the clamping network. 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.
