CHL8318-20 - Digital Multi-Phase Buck Controller

Datasheet Summary

Description

The CHL8318-20 is an 8-phase digital synchronous buck controller for core regulation of high-performance Intel® VR11.1 and VR11.0 platforms.

The CHL8318-20 is fully compliant with VR11.1 including Power Status Indicator (PSI) and for improved light load efficiency and accurate current output (IMON).

Features

  • Intel VR11.x compliant Digital PWM Controller.
  • Programmable 1-phase to 8-phase operation.
  • Customized Digital Over-Clocking features an easy-to-use SMBus Gamer command and a Gamer VID control up to 2.3V, Gamer Vmax, VID Override or Track, Digital Load-Line Adjust, Gamer OC/OVP, Gamer OFF pin and Gamer OTP.
  • IR Efficiency Shaping features a Variable Gate Drive and Dynamic Phase Control.
  • 1-phase to 4-phase PSI for Light Loads.
  • Adaptive Transient Algorithm minimizes cap.
