ADP3180中文资料6-Bit Programmable 2-, 3-, 4-Phase Synchronous Buck Controller数据手册ADI规格书

描述 Description

GENERAL DESCRIPTION
The ADP3180 is a highly effi cient multiphase synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high per formance Intel processors. It uses an internal 6-bit DAC to read a voltage identifi cation (VID) code directly from the processor, which is used to set the output voltage between 0.8375 V and 1.6 V, and uses a multimode PWM architecture to drive the logic level outputs at a programmable switching frequency that can be
optimized for VR size and efficiency.FEATURES
Selectable 2-, 3-, or 4-Phase Operation at up to 1 MHz per Phase
\u000114.5 mV Worst-Case Differential Sensing Error over Temperature
Logic-Level PWM Outputs for Interface to External High Power Drivers
Active Current Balancing between All Output Phases
Built-In Power Good/Crowbar Blanking Supports 
  On-the-Fly VID Code Changes
6-Bit Digitally Programmable 0.8375 V to 1.6 V Output
Programmable Short Circuit Protection with  Programmable Latch-Off Delay

APPLICATIONS
Desktop PC Power Supplies for:
 Next Generation Intel® Processors
 VRM Modules
