The MP2855 is a dual-loop, digital, multi-phase controller that provides power for the core of the AMD SVI2 2.0 platform. The device can work with MPS’s Intelli-PhaseTM products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2855 can be configured with up to 9-phase operation for rail 1 and up to 4-phase operation for rail 2.
The MP2855 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 (IOUT) through the CS output from Intelli-PhaseTM products.
The MP2855 is based on unique, digital, multi-phase nonlinear 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 load transient, the power loop compensation is easy to configure.
The device is available in a TQFN-40 (5mmx5mm) package.
