电流模式 PWM 控制器

VPC218X 系 列 是 适 用 于 多 种 拓 扑 结 构（ Flyback\\Buck\\ Boost ） 和 输 出 电 压 反 馈 方 式（SSR\\PSR\\电阻分压）的高度集成电源控制芯片。集成了低至 4V、高至 100V 的超宽范围启动电路。内部集成的防倒灌二极管可防止电流从 VDD 端反流到 VIN端。\r\n\r\nVPC218X 内部集成了电流采样差分放大器来大幅提高采样信噪比，将 CS 端口的限流阈值电压降低至156mV，可大幅减小电流采样电路的功耗，采用无电流互感器设计，从而降低成本和提高可靠性。\r\n\r\nVPC218X 控制器在较重负载时固定工作于设定好的最大 • 超宽输入电压范围 4V~100V 启动电路\r\n• 限流阈值电压 156mV 和 500mV 可选\r\n• 轻负载逐级模拟降频优化效率曲线\r\n• 使能关断电流低至 0.1uA\r\n• 电流感测信号的前沿消隐\r\n• 可精确设置输入欠压保护及回差\r\n• CCM/DCM 模式下内置环路 PSR 控制\r\n• MSOP10 超小体积封装形式;
