ADP5023CP-EVALZ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ADP5023CP-EVALZ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(jìn)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(jì)為控制外部電源開關(guān)）之類的器件均包括在內(nèi)。

GENERAL DESCRIPTION

The ADP5023 combines two high performance buck regulators and one low dropout (LDO) regulator 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, the buck regulators operate in PWM mode when the load current is above a predefined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM) improving the light-load efficiency.
