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.

Features  
• Fixed−Frequency Current−Mode Operation with Ramp  
Compensation and Skip Cycle in Standby Condition  
• Timer−Based Fault Protection for Improved Overload Detection  
• “Soft−Skip Mode” Technique for Optimal Noise Control in Standby  
• Internal High−Voltage Startup Current Source for Lossless Startup  
• "5% Current Limit Accuracy over the Full Temperature Range  
• Adjustable Skip Level  
• Internal Latch for Easy Implementation of Overvoltage and  
Overtemperature Protection  
• Frequency Jittering for Softened EMI Signature  
• +500 mA/−800 mA Peak Current Drive Capability  
• Sub−100 mW Standby Power can be Achieved  
• Pin−to−Pin Compatible with the Existing NCP120X Series  
• This is a Pb−Free Device
