NCP1271D100R2G
The NCP1271 represents a new, pin to pin compatible, generation 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 startupFET. 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
