NCP1271 Standby PWM Controller

DATA SHEET www.onsemi.com Soft-Skipt Mode Standby PWM Controller with Adjustable Skip Level and External Latch NCP1271 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 a.
