📥 Download Datasheet

General Description

The MP2965 is a dual-loop, digital, multi-phase controller that provides power for the core of the Intel VR13.HC platform and AVSBus control CPU.

The MP2965 can work with MPS’s IntelliPhase products to complete the multi-phase voltage regulator (VR) solution with minimal external components.

The MP2965 can be configured with up to 7-phase operation for Rail 1 and up to 3-phase operation for Rail 2.

Overview
