具有 16V/10V VCC UVLO 和 6.75V/5.5V PWM UVLO、温度范围为 -40°C 至 85°C 的 PFC/PWM 组合控制器

The UCC2850x family provides all of the control functions necessary for an active power-factor-corrected preregulator and a second-stage dc-to-dc converter. The controller achieves near-unity power factor by shaping the ac input line current waveform to correspond to the ac input-line voltage using • Combines PFC and Downstream Converter Controls\n• Controls Boost Preregulator to Near-Unity Power Factor\n• Accurate Power Limiting\n• Improved Feedforward Line Regulation\n• Peak Current-Mode Control in Second Stage\n• Programmable Oscillator\n• Leading-Edge/Trailing-Edge Modulation for Reduced O;
