The EVQ72957FS-86960A-02A evaluation board is a 4-rail, multi-phase voltage regulator (VR) solution. It supports the MPQ72957FS-AEC1 and MPQ86960A. This combined solution acts as a multi-phase, synchronous buck converter with minimal external components.

The EVQ72957FS-86960A-02A aims to supply power for four rails. The phase number of the four rails can be configured flexibly, with a maximum phase number of 8, 4, 2, and 2 for rail A, rail B, rail C, and rail D, respectively.

As the core controller for the EVQ72957FS-86960A-02A, the MPQ72957FS-AEC1 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 I²C interface.

The MPQ72957FS-AEC1 is based on unique, digital, multi-phase nonlinear control to provide fast transient response to the load transient with minimal output capacitance (C_OUT). With only one power loop control method for both the steady state and load transient, power loop compensation is simple to configure.

The EVQ72957FS-86960A-02A datasheet provides the test set-up, schematic, bill of materials, and layout required to evaluate the VR solution.
