ADP2102開發(fā)板套件編程器的評估板-DC/DC與AC/DC（離線）SMPS規(guī)格書PDF中文資料

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

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.
