单相同步 Buck 控制器

RT8209L/M PWM 控制器具有转换效率高、卓越的瞬态响应特性和高精度的电压输出，可将笔记本电脑的电池高电压转换为 CPU 内核、图形处理器、I/O 和芯片组需要的低压电源。由于采用固定导通时间控制技术，它可很容易地面对输入/输出比很宽的环境，对负载瞬变提供 100ns 的“即时”响应速度，同时维持基本恒定的工作频率。RT8209L/M 不使用传统的电流模式 PWM 控制架构中的电流检测电阻，降低了成本，提高了效率。其效率的进一步提升还来自于其具有的驱动大型同步整流 MOSFET 的能力，使其可将电池高电压直接转换为系统需要的电压，这也使得效率实现了最大化，可为 CPU 内核、芯片组、D • 极高的效率\n• 4700ppm/°C 电流检测\n• 全输入、负载范围内 1% VFB 精度\n• 电阻可设定工作频率\n• 集成负电流限制器\n• 过压保护/欠压保护\n• Power Good 指示\n• 符合 RoHS 规范，不含卤素\n;
