ADM8829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

ADM8829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ADM8829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 ADM8828/ADM8829 is a charge-pump voltage inverter which may be used to generate a negative supply from a positive input. Input voltages ranging from +1.5 V to +5.5 V can be inverted into a negative –1.5 V to –5.5 V output supply. This inverting scheme is ideal for generating a negative rail in single power-supply systems. Only two small external capacitors are needed for the charge pump. Output currents up to 25 mA with greater than 99 efficiency are achievable.

The ADM8828 also features a low power shutdown (SHDN) pin. This can be used to disable the device and reduce the quies cent current to 20 nA.

The ADM8828/ADM8829 is available in a 6-lead SOT-23 package.
