MP29612-A

Dual-Loop, Digital, 12-Phase Controller with SVI3 Interface

详情

The MP29612-A is a dual-rail, digital, multi-phase controller that provides power for SVI3 core power. The device can work with MPS’s Intelli-Phase^TM products to complete the multi-phase voltage regulator (VR) solution with minimum external components. It can be configured to maximum 12-phase operation for rail 1, and maximum 6-phase operation for rail 2.

The controller 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 MP29612-A can monitor and report the output current (I_OUT) via the current-sense output of the Intelli-Phase^TM devices.

It is based on a unique, digital, multi-phase, nonlinear control to provide fast transient response with minimal output capacitors. With only one power loop control method for both steady state and load transient, power loop compensation is very easy to configure.

The MP29612-A is available in a TQFN-48 (6mmx6mm) package.
