ADP5033ACBZ-1-R7集成電路（IC）的線性穩(wěn)壓器控制器規(guī)格書PDF中文資料

ADP5033ACBZ-1-R7屬于集成電路（IC）的線性穩(wěn)壓器控制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADP5033ACBZ-1-R7穩(wěn)壓器 - 線性 + 開關(guān)此產(chǎn)品族中的產(chǎn)品用于構(gòu)建執(zhí)行 DC-DC 轉(zhuǎn)換或電壓調(diào)節(jié)功能的電路，采用的是開關(guān)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(chǎn)品的主要目的是將開關(guān)模式技術(shù)的效率優(yōu)勢與線性穩(wěn)壓技術(shù)的低噪聲特性結(jié)合在一起。

GENERAL DESCRIPTION

The ADP5033 combines two high performance buck regulators and two low dropout regulators (LDO) in a tiny, 16-ball, 2 mm × 2 mm WLCSP to meet demanding performance and board space requirements.

The two bucks operate out of phase to reduce the input capacitor requirement and noise.

The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5033 LDO extend the battery life of portable devices. The ADP5033 LDOs maintain power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage.

The regulators in the ADP5033 are activated by the ENA and ENB pins. The specific channels controlled by ENA and ENB are set by factory programming. A high voltage level applied to the enable pins activates the regulators. The default output voltages are factory programmable and can be set to a wide range of options.
