ADP2323屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADP2323DC-DC 開關(guān)控制器PMIC（電源管理集成電路）DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC，其配置為生成高于（突升或步升）或低于（突降或步降）輸入電源的輸出電源電壓。其他拓?fù)浣Y(jié)構(gòu)可能包括：降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。

GENERAL DESCRIPTION

The ADP2323 is a full featured, dual output, step-down dc-to-dc regulator based on current-mode architecture. The ADP2323 integrates two high-side power MOSFETs and two low-side drivers for the external N-channel MOSFETs. The two pulse-width mod ulation (PWM) channels can be configured to deliver dual 3 A outputs or a parallel-to-single 6 A output. The regulator operates from input voltages of 4.5 V to 20 V, and the output voltage can be as low as 0.6 V.
