NCP1271
Soft-Skipt Mode 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. 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
Typical Applications
AC−DC Adapters for Notebooks, LCD Monitors
Offline Battery Chargers
Consumer Electronic Appliances STB, DVD, DVDR
