MP2965
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 Intelli Phase products to plete the multi-phase voltage regulator (VR) solution with minimal external ponents. The MP2965 can be configured with up to 7-phase operation for Rail 1 and up to 3-phase operation for Rail 2.
The MP2965 provides an on-chip EEPROM to store and restore device configurations. Device configurations and fault parameters can be easily programmed or monitored via the PMBus/I2C interface. The MP2965 can monitor and report output current through the CS output from the Intelli-Phase products.
The MP2965 is based on a unique, digital, multi-phase, non-linear control to provide a fast transient response to the load transient with minimal output capacitors. With only one power loop control method for both steady state and the load transient, the power loop pensation is very easy to...
