MP29608-A

Dual-Loop, Digital, 8-Phase Controller with SVI3 Interface

概要

The MP29608-A is a dual-rail, digital, multi-phase controller that provides power for SVI3 core power. The device can work with MPS’s Intelli-Phase^TM products to complete the multi-phase voltage regulator (VR) solution with minimum external components. It can be configured to maximum 8-phase operation for rail 1 and a maximum 4-phase operation for rail 2.

The controller 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 MP29608-A can monitor and report the output current (I_OUT) by sensing the current-sense output of the Intelli-Phase^TM devices.

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

The MP29608-A is available in a TLGA-40 (5mmx5mm) package.
