MPQ29164-AEC1

MPQ29164-AEC1

Digital, 6-Phase Controller with I²C Interface for IMVP8/9/9.1, AEC-Q100 Qualified

概要

The MPQ29164-AEC1 is a dual-rail, multi-phase digital voltage regulator (VR) controller, and it is compliant with IMVP8/IMVP9/IMVP9.1 for Intel microprocessors.

The MPQ29164-AEC1 can work with MPS’s Intelli-Phase^TM products to complete the multi-phase VR solution with minimal external components. The device can be configured for single-rail operation, and can operate in low quiescent current (I_Q) mode. Rail A is configurable up to 4 phases, while rail B is configurable up to 2 phases.

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 I²C interface. The MPQ29164-AEC1 can monitor and report the output current (I_OUT) through the Intelli-Phase^TM current-sense (CS) output.

The MPQ29164-AEC1 is based on unique, digital, multi-phase nonlinear control to provide fast transient response with minimal output capacitors. With only one power loop control method for both the steady state and load transient, power loop compensation is simple to configure.

The MPQ29164-AEC1 is available in a TQFN-48 (6mmx6mm) package, and is available in AEC-Q100 Grade 1.
