支持 50Hz 至 400Hz 范围内线路频率、温度范围为 –40°C 至 85°C 的双极性 CCM PFC 控制器

The UC1854 provides active-power factor correction for power systems that otherwise would draw non-sinusoidal current from sinusoidal power lines. This device implements all the control functions necessary to build a power supply capable of optimally using available power-line current while minimizi • Control Boost PWM to 0.99 Power Factor\n• Limit Line-Current Distortion to;
