Description
The MP2882 is a dual-loop, digital, multi-phase controller that provides power for the memory and system-on-chip (SoC). The MP2882 can work with MPS’s Intelli-PhaseTM products to complete the multi-phase voltage regulator (VR) solution with a minimal number of external components. The MP2882 can be configured for up to 16-phase operation on rail 1 and up to 8-phase operation on rail 2.
The MP2882 provides 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 devices.
The MP2882 is based on unique, digital, multi-phase 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 simple to configure.
The MP2882 is available in a TQFN-56 (7mmx7mm) package.
