MP2953B

The MP2953B is a digital multi-phase controller that provides power for the core of the INTEL VR12.5 platform. It works with MPS’ Intelli-Phase products to complete the multi-phase VR solution with minimal external components. It can be configured for 1 ~ 6 phase operation.

The MP2953B provides on-chip EEPROM to store and restore device configurations. Device configurations and fault parameters are easy to program or monitor using the PMBus interface. The MP2953B monitors and reports the output current through CS output from Intelli-Phase products.
The MP2953B is based on a unique digital multi-phase, non-linear control to provide fast transient response to load transient with minimal output capacitors. With only one power loop control method for both steady state and load transient, the power loop compensation is easily configured.
