NCP1271  
Soft−Skipt Mode Standby  
PWM Controller with  
Adjustable Skip Level and  
External Latch  
http://onsemi.com  
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 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.
