温度范围为 –40°C 至 85°C 的双极性转换模式 PFC 控制器

The UC1852 provides a low-cost solution to active power-factor correction (PFC) for systems that would otherwise draw high peak current pulses from AC power lines. This circuit implements zero-current switched boost conversion, producing sinusoidal input currents with a minimum of external component • Low-Cost Power Factor Correction\n• Power Factor Greater Than 0.99\n• Few External Parts Required\n• Controlled On-Time Boost PWM\n• Zero-Current Switching\n• Limited Peak Current\n• Min and Max Frequency Limits\n• Starting Current Less Than 1mA\n• High-Current FET Drive Output\n• Under-Voltage Lo;
