概览

ADP3198 是一款高能效、多相位、同步、降压开关稳压器控制器，适用于将 12 V 主电源转换为高性能 Intel 处理器所需的芯电源电压。它使用内部 8 位 DAC 直接从处理器读取电压标识 (VID) 码，用于设置 0.5 V 到 1.6 V 之间的输出电压。

  • 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
