MPQ2977 Datasheet | Monolithic Power Systems

DESCRIPTION The MPQ2977 is a dual-rail, multi-phase digital voltage regulator (VR) controller for autonomous driving applications. The MPQ2977 can work with MPS’s Intelli-Phase TM products to plete the multi-phase VR solution with minimal external ponents. The MPQ2977 is scalable up to six 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 using the PMBus interface. The MPQ2977 can monitor and report the output current (IOUT) through the Intelli-Phase TM current-sense (CS) output. The MPQ2977 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 pensation is simple to configure. The MPQ2977 is available in a TQFN-40 (6mmx6mm) package.
