ADP2102开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF中文资料

ADP2102属于开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS。由亚德诺半导体技术有限公司制造生产的ADP2102评估板 - DC/DC 与 AC/DC（离线）SMPS该系列产品提供了一种方便的方法，可对开关模式电源转换所用的器件（包括 DC-DC 和 AC-DC 型）进行性能或特性评估。“稳压器”（包含内部电源开关装置）和“控制器”（设计为控制外部电源开关）之类的器件均包括在内。

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.
