MP2869A

MP2869A

Dual-Loop, Digital, 16-Phase Controller with SVI3 Interface for AMD

概要

The MP2869A is a dual-rail, digital, multi-phase controller that provides power for AMD SVI3 core power. The device can work with MPS’s Intelli-Phase^TM products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2869A can be configured to maximum 16-phase operation for rail 1, and maximum 8-phase operation for rail 2.

The MP2869A provides an on-chip non-volatile memory (NVM) to store and restore device configurations. Device configurations and fault parameters can be easily configured or monitored via the PMBus/I²C interface. The device can monitor and report the output current (I_OUT) via the current-sensing output of the Intelli-Phase^TM devices.

The MP2869A is based on a unique, digital, multi-phase, nonlinear control to provide fast transient response to load transients with minimal output capacitors. With only one power-loop control method for steady state and load transients, power loop compensation is very easy to configure.

The MP2869A is available in a TQFN-56 (7mmx7mm) package.
