ADP3196集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

ADP3196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ADP3196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。

GENERAL DESCRIPTION

The ADP31961 is a highly efficient multiphase synchronous buck switching regulator controller optimized for converting a

12 V main supply into the core supply voltage required by high performance Advanced Micro Devices, Inc. (AMD) processors. It uses an internal 6-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.3750 V and 1.55 V.

FEATURES

Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase

±10 mV worst-case differential sensing error over temperature

Logic-level PWM outputs for interface to external high power drivers

Enhanced PWM flex mode for excellent load transient performance

Active current balancing between all output phases

Built-in power-good/crowbar blanking supports on-the-fly VID code changes

Digitally programmable 0.3750 V to 1.55 V output

Programmable short-circuit protection with programmable latch-off delay

APPLICATIONS

Desktop PC power supplies for next generation

AMD processors

VRM modules
