Description
The MP2853 is a dual-loop, digital, multi-phase controller that provides power for the core of the AMD SVI 2.0 platform. The MP2853 can work with MPS Intelli-Phase products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2853 can be configured with up to 4-phase operation for Rail 1 and up to 2-phase operation for Rail 2.
The MP2853 provides an on-chip EEPROM to store and restore device configurations. Device configurations and fault parameters can be programmed easily or monitored via the PMBusTM/I2C interface. The MP2853 can monitor and report output current through the CS output from Intelli-Phase products.
The MP2853 is based on a unique, digital, multi-phase, non-linear control to provide fast transient response to the 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 very easy to configure.
The MP2853 is available in a QFN-40 (5mmx5mm) package.
