MPQ2967-AEC1

Dual-Rail, Digital, 4-Phase Controller with PMBus Interface, AEC-Q100 Qualified

Datasheet

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 (I_OUT) through the Intelli-Phase^TM current-sense (CS) output.

The MPQ2967 is based on unique, digital, multi-phase 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.
