ADP2108ACBZ-1.5-R7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

ADP2108ACBZ-1.5-R7屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關穩(wěn)壓器。由亞德諾半導體技術有限公司制造生產的ADP2108ACBZ-1.5-R7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。

GENERAL DESCRIPTION

The ADP2108 is a high efficiency, low quiescent current stepdown dc-to-dc converter manufactured in two different packages. The total solution requires only three tiny external components. It uses a proprietary, high speed current mode, constant frequency PWM control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP2108 has a power save mode that reduces the switching frequency under light load conditions.
