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.
