快速关断智能整流器，无需辅助绕组

MP6908L 是一款低压降二极管控制 IC。驱动外部开关管时，MP6908L 可取代高效率反激变换器中的肖特基二极管。MP6908L 可将外部同步整流器（SR）MOSFET 的导通压降调节至大约 40mV，一旦电压变为负，则开关关断。\n\n MP6908L 可以为具有低输出电压的电池充电应用或在短路输出状态下以及高侧 SR 配置生成自身的电源电压。可配置振铃检测电路可防止 MP6908L 在断续导通模式（DCM）或准谐振工作期间在 VDS 振荡后发生误关断。\n\n MP6908L 采用节省空间的 TSOT23-6 封装。 • 宽输出电压范围低至 0V，无短路电流经过体二极管\n• 副边高端或低端整流无需辅助绕组\n• 振铃检测可防止 DCM 和准谐振工作时误导通\n• 可驱动标准和逻辑电平 SR MOSFET\n• 符合能效之星要求\n• 30ns 快速关断和接通延迟\n• 100µA 静态电流\n• 支持 DCM、CCM 和准谐振工作模式\n• 支持副边高端和低端整流\n• 采用 TSOT23-6 封装;
