L6926集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

L6926屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L6926穩(wěn)壓器 - DC-DC 開關(guān)穩(wěn)壓器DC-DC 開關(guān)穩(wěn)壓器 PMIC（電源管理集成電路）產(chǎn)品族中的產(chǎn)品是元器件級設(shè)備，用于需要穩(wěn)定 DC 輸入電壓和/或?qū)⑵滢D(zhuǎn)換為不同幅度的輸出電壓的應(yīng)用。這些器件與稱為“控制器”PMIC 的類似產(chǎn)品的區(qū)別在于集成了主開關(guān)元件，設(shè)備提供的電力會通過該元件。

Description

The device is dc-dc monolithic regulator specifically designed to provide extremely high efficiency.

L6926 supply voltage can be as low as 2V allowing its use in single Li-ion cell supplied applications. Output voltage can be selected by an external divider down to 0.6V.

Duty Cycle can saturate to 100 allowing low drop-out operation.
