单级反激和边界模式 PFC 控制器，用于照明

FL7930B 是一款有源功率因数校正 (PFC) 控制器，用于在临界导通模式 (CRM) 下运行的升压 PFC 应用。它使用比较内部斜坡信号和误差放大器输出的电压模式PWM来生成MOSFET关断信号。由于电压模式CRM PFC控制器无需整流AC线路电压信息，因此电流模式CRM PFC控制器所必需的输入电压传感网络的功率损耗就得到了节省。FL7930B 提供过压保护 (OVP)、反馈开路保护、过流保护 (OCP)、输入电压缺失检测和欠压闭锁保护 (UVLO)。附加的 OVP 引脚，因INV引脚处连接的电阻损坏导致输出电压超过过压保护电平时，可关断升压功率级。如果 INV 引脚电压小于 0.45 • 附加 OVP 检测引脚\n• VIN 缺失检测\n• 最大开关频率限制\n• 内部软启动和无过冲启动\n• 内部总谐波失真 (THD) 优化器\n• 准确可调的输出过压保护\n• 开路反馈保护和禁用功能\n• 零电流检测器 (ZCD)\n• 150µs 内部启动定时器\n• MOSFET 过流保护 (OCP)\n• 带 3.5V 滞洄的欠压闭锁\n• 低启动和工作电流\n• 具有高态箝位的图腾柱输出\n• +500/-800mA 峰值栅极驱动电流\n• 8 引脚小尺寸封装 (SOP);
