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 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...
