CHL8328 - DIGITAL MULTI-PHASE GPU BUCK CONTROLLER

Download the CHL8328 datasheet PDF. This datasheet also covers the CHL8326 variant, as both devices belong to the same digital multi-phase gpu buck controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The CHL8326/8 are dual-loop digital multi-phase buck controllers.

The CHL8326 drives up to 6 phases and the CHL8328 drives up to 8 phases.

The CHL8326/8 is fully Intel® VR12 and AMD® SVI/PVI compliant on both loops and provides a Vtt tracking function for DDR memory.

Key Features

  • 6-phase & 8-phase dual output PWM Controller.
  • Phases are flexibly assigned between Loops 1 & 2.
  • Intel® VR12, AMD® SVI/PVI/G34 & Memory modes.
  • Overclocking & Gaming Mode with Vmax setting.
  • Switching frequency from 200kHz to 1.2MHz per phase.
  • CHiL Efficiency Shaping Features including Variable Gate Drive, Dynamic Phase Control.
  • Programmable 1-phase or 2-phase for Light Loads and Active Diode Emulation for Very Light Loads.
  • CHiL Adaptive Transient Algorithm.
