The MP29540 is a digital controller that supports high-current, multi-phase voltage regulators (VRs). The MP29540 works together with external power stages to make a hybrid buck or standard multi-phase VR solutions. The MP29540 can sense the current via the inductor's DC resistance (DCR).

The MP29540 can be configured with up to 8-phase operation to support 4 blocks of hybrid buck topology with an external AND gate, or up to 6-phase operation to support 3 blocks of hybrid buck topology with an internal AND gate (PWMx_xN pins).

The MP29540 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 MP29540 is based on a 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 response, the power loop compensation is very easy to configure.

The MP29540 is available in a TLGA-40 (5mmx5mm) package.
