Product Description

Soft−SkipMode Standby PWM Controller with Adjustable Skip Level and External Latch
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.
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
Typical Applications
•AC−DC Adapters for Notebooks, LCD Monitors
•Offline Battery Chargers
•Consumer Electronic Appliances STB, DVD, DVDR
