ADP5037CP-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

ADP5037CP-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ADP5037CP-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 ADP5037 combines two high performance buck regulators and two low dropout (LDO) regulators in a small, 24-lead 4 mm × 4 mm LFCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low and the load is above a predefined threshold, the buck regulators operate in PWM mode. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving the light-load efficiency.
