ADP2102屬于開發(fā)板套件編程器的評估板-DC/DC與AC/DC（離線）SMPS。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADP2102評估板 - DC/DC 與 AC/DC（離線）SMPS該系列產(chǎn)品提供了一種方便的方法，可對開關(guān)模式電源轉(zhuǎn)換所用的器件（包括 DC-DC 和 AC-DC 型）進行性能或特性評估?！胺€(wěn)壓器”（包含內(nèi)部電源開關(guān)裝置）和“控制器”（設(shè)計為控制外部電源開關(guān)）之類的器件均包括在內(nèi)。

GENERAL DESCRIPTION

The ADP2102 is a synchronous step-down dc-to-dc converter that converts a 2.7 V to 5.5 V unregulated input voltage to a lower regulated output voltage with up to 95 efficiency and 1 accuracy. The low duty cycle capability of the ADP2102 is ideal for USB applications or 5 V systems that power up submicron subvolt processor cores. Its 3 MHz typical operating frequency and excellent transient response allow the use of small, low cost 1 μH inductors and 2.2 μF ceramic capacitors.
