NCP1271 Description
Soft-Skipt Mode Standby PWM Controller with Adjustable Skip Level and External Latch NCP1271 The NCP1271 represents a new, pin to pin patible, 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...
