Overview

ADP3198 は高効率な多相の同期降圧レギュレータ・コントローラで、12 V 主電源を高性能インテル・プロセッサの要求するコア電源電圧に変換できるよう最適化されています。内部 8 ビット DAC を使用して、プロセッサから電圧識別 (VID) コードを直接読み取ります。これは、出力電圧を 0.5 V 〜 1.6 V に設定するために使用されます。

  • VR Modules
  • Desktop Computers
  • Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase
  • ±11 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 0.5 V to 1.6 V output supports both VR10.x and VR11 specifications
  • Programmable short-circuit protection with programmable latch-off delay
