DESCRIPTION

The MPQ2967 is a digital, dual-rail, multi-phase

controller for autonomous driving applications. It

can work with MPS’s Intelli-PhaseTM products to

complete the multi-phase voltage regulator (VR)

solution with minimal external components. The

device can be configured for up to 4 phases

between two rails.

The on-chip, multiple-time programmable (MTP)

memory stores and restores device

configurations. Device configurations and fault

parameters can be configured or monitored via

the PMBus interface. The MPQ2967 can monitor

and report the output current (IOUT) through the

Intelli-PhaseTM current-sense (CS) output.

The MPQ2967 is based on unique, digital, multiphase nonlinear control to provide fast transient

response to a load step with minimal output

capacitors. With only one power loop control

method for both the steady state and load

transient response, power loop compensation is

simple to configure.

The MPQ2967 is available in a TQFN-40

(6mmx6mm) package.
