CHL8325B - DIGITAL MULTI-PHASE BUCK CONTROLLER

Download the CHL8325B datasheet PDF. This datasheet also covers the CHL8325A variant, as both devices belong to the same digital multi-phase buck controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The CHL8325A/B are dual-loop digital multi-phase buck controllers that drive up to 5 phases.

The CHL8325A/B is fully Intel® VR12 and AMD® SVI compliant on both loops and provides a Vtt tracking function for DDR memory.

NVM storage saves pins and enables a small package size.

Key Features

  • 5-phase dual output PWM Controller Phases are flexibly assigned between Loops 1 & 2 Intel® VR12, AMD® SVI/G34 & Memory MPoL modes Dual OCP support for I-spike enhanced AMD CPUs SMB_Alert Pin for Servers PMBus Address pin or Variable Gate Drive (CHL8325A) 2nd Temperature Sense for VR12 Desktop (CHL8325B) Overclocking & Gaming Mode with Vmax setting Switching frequency from 200kHz to 1.2MHz per phase CHiL Efficiency Shaping Features including Variable Gate Drive (CHL8325A only), Dynamic Phase Cont.
