具有 10.5V/10V UVLO、适用于 50Hz 至 400Hz 线路频率、温度范围为 –40°C 至 85°C 的增强型双极性 CCM PFC 控制器

The UC3854A/B products are pin compatibleenhanced versions of the UC3854. Like the UC3854, 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 correspon • Controls Boost PWM to Near-Unity Power Factor\n• Limits Line Current Distortion To AC Offset (Eliminates External Resistor), 0 V to 5 V Multout Common-Mode Range\n• VREF GOOD Comparator\n• Faster and Improved Accuracy ENABLE Comparator \n• UVLO Options (16 V/10 V or 10.5 V/10 V)\n• 300-µA Start-Up;
