ADP5040CP-1-EVALZ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

ADP5040CP-1-EVALZ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ADP5040CP-1-EVALZ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 ADP5040 combines one high performance buck regulator and two low dropout regulators (LDO) in a small 20-lead LFCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulator enables the use of tiny multilayer external components and minimizes board space.
