MP2882A

Dual-Loop, Digital, 16-Phase Controller with PMBus Interface for AVSBus

Description

The MP2882A is a dual-loop, digital, multi-phase controller that provides power for the memory and system-on-chip (SoC). The device can work with MPS’s Intelli-Phase^TM products to complete the multi-phase voltage regulator (VR) solution with a minimal number of external components. The MP2882A can be configured for up to 16-phase operation on rail 1 and up to 8-phase operation on rail 2.

The MP2882A 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 (I_OUT) through the current-sensing (CS) output from Intelli-Phase^TM devices.

The MP2882A is based on unique, digital, multiphase control to provide fast transient response to the load transient with a minimal number of output capacitors. With only one power loop control method for both steady state and load transients, power loop compensation is simple to configure.

The MP2882A is available in a TQFN-56 (7mmx7mm) package.
