Continuous conduction mode (CCM) PFC controller with high voltage startup

L4985是一款用于升压转换器的峰值电流模式PFC控制器，采用专有的乘法器“模拟器”，除了创新型THD优化器，还保证在所有工条件下具有非常低的总谐波失真（THD）性能。该器件采用引脚SO封装，在符合EN61000-3-2和JEIDA-MITI标准的应用中为以CCM模式运行的升压PFC预调节器提供高性能/低组件数的解决方案，功率范围从几百瓦到几千瓦。\n\n 由于采用专有的关断时间调制器，该器件能够在所有工作条件下以准固定频率运行。提供两个选项：A为65 kHz，B为130 kHz。\n\n 800V高压启动功能块还包括用于将EMI滤波器的X电容降低到安全水平的电路。这使得该装置能够满足安全规定 • 峰值电流模式，以CCM模式运行 \n• 800 V高压启动，具有集成的输入电压感应 \n• 有源输入滤波电容放电 \n• 专有乘法器“模拟器”，在所有工作条件（CCM和 DCM）下的最小线电流THD \n• 精简的外部组件 \n• 保护：反馈回路故障、OVP、OCP、电感饱和、过压、欠压（符合医疗SMPS标准） \n• 电感电流感应• 禁用和低功耗功能 \n• 浪涌电流监测 \n• 通过软启动实现平滑的启动 \n• 1.2%（@ Tj = 25 °C）内部参考电压 \n• 65 kHz（A版本）和130 kHz（(B版本）开关频率 \n• SO8封装;
