ADP3211AMNR2G屬于集成電路（IC）的特殊用途穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的ADP3211AMNR2G特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機管理等。

The ADP3211 is a highly efficient, single?phase, synchronous buck switching regulator controller. With its integrated driver, the ADP3211 is optimized for converting the notebook battery voltage to the supply voltage required by high performance Intel chipsets. An internal 7?bit DAC is used to read a VID code directly from the chip?set or the CPU and to set the GMCH render voltage or the CPU core voltage to a value within the range of 0 V to 1.5 V.
