MC34167TH集成電路（IC）的穩(wěn)壓器-DC-DC開關穩(wěn)壓器規(guī)格書PDF中文資料

MC34167TH屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關穩(wěn)壓器。由安森美半導體公司制造生產的MC34167TH穩(wěn)壓器 - DC-DC 開關穩(wěn)壓器DC-DC 開關穩(wěn)壓器 PMIC（電源管理集成電路）產品族中的產品是元器件級設備，用于需要穩(wěn)定 DC 輸入電壓和/或將其轉換為不同幅度的輸出電壓的應用。這些器件與稱為“控制器”PMIC 的類似產品的區(qū)別在于集成了主開關元件，設備提供的電力會通過該元件。

The MC34167, MC33167 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc–to–dc converters. This series was specifically designed to be incorporated in step–down and voltage–inverting configurations with a minimum number of external components and can also be used cost effectively in step–up applications.
