ADP5023集成電路（IC）的線性穩(wěn)壓器控制器規(guī)格書PDF中文資料

ADP5023屬于集成電路（IC）的線性穩(wěn)壓器控制器。由亞德諾半導體技術有限公司制造生產的ADP5023穩(wěn)壓器 - 線性 + 開關此產品族中的產品用于構建執(zhí)行 DC-DC 轉換或電壓調節(jié)功能的電路，采用的是開關模式和線性穩(wěn)壓器功能的組合。雖然具體的拓撲各不相同，但此類產品的主要目的是將開關模式技術的效率優(yōu)勢與線性穩(wěn)壓技術的低噪聲特性結合在一起。

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.
