TPS54418

illustrate

该TPS54418器件是一个全功能的6伏，4安培，电流模式转换器的同步下跌一步两个集成的MOSFET。

通过集成的TPS54418使MOSFET的小设计，实施电流模式控制，以减少外部元件数量，减少使高达2 MHz的开关频率电感尺寸，并尽量减少一个小型3mm × 3mm的热增强型QFN封装集成电路的足迹。

该TPS54418提供一个准确的± 1％电压基准（VREF）随温度的精确调节各种负载。

Efficiency is maximized by the integrated 30 meters MOSFETs and power consumption 350μA typical supply current. Using the Enable pin, the shutdown supply current is reduced to 2 microamps into a shutdown mode.
