增强型产品高级高功率因数前置稳压器

The UC2854B products are pin compatible enhanced versions of the UC2854. Like the UC2854, these products provide all of the functions necessary for active power factor corrected preregulators. The controller achieves near unity power factor by shaping the ac-input line current waveform to correspond • Controlled Baseline\n• Extended Temperature Performance of -55°C to 125°C \n• Enhanced Product-Change Notification \n• Controls Boost PWM to Near-Unity Power Factor \n• Faster and Improved Accuracy ENABLE Comparator \n• 300-µA Start-Up Supply Current;
