2 to 4-Phase Synchronous Buck Controller

Favorite

Overview

The ADP3196 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.

  • Power supplies for AMD processors
  • Desktop PCs
  • Selectable 2- ,3- or 4- Phase Operation at up to 1 MHz per Phase
  • Logic-Level PWM Outputs for Interface to External High Power Dirvers
  • Active Current Balancing between All Output Phases
  • ±10 mV Worst-Case Diffential Sensing Error over Temperture
  • Enhanced PWM Flex-Mode™ for Excellent Load Transient Performance
  • Programmable Short-Circuit Protection with Programmable Latch-Off Delay
  • Digitally Programmable 0.3750 V to 1.55 V Output
  • Built-in Power Good/Crowbar Blanking Supports on-the-fly VID Code Changes
  • Power supplies for VRM modules
