This use case discusses the application of the MPQ86940 and MPQ2977-AEC1 in automotive high-performance computing (HPC).

The MPQ86940 Intelli-Phase^TM solution combined with the MPQ2977-AEC1 multi-phase controller can be used to design a multi-phase voltage regulator (VR) with digital control, enabling efficient and adaptive power delivery that optimizes the performance of automotive HPC systems.

Automotive power management in high-performance computing tasks such as autonomous driving, robotaxis, software-defined vehicles, and ADAS rely on HPC systems. As automotive HPC systems are scaled up, the corresponding increase in power consumption and resulting heat generation can lead to issues, including damaged components that impact reliability, higher cooling costs, and increased carbon footprint. With the broad application of automotive HPC systems in vehicle engineering and testing as well as in machine learning algorithms that enable high-end infotainment systems and autonomous driving, it is crucial to evolve the power management and efficiency of automotive HPC.

The MPQ86940 Intelli-Phase^TM solution combined with the MPQ2977-AEC1 multi-phase controller can be used to design a multi-phase voltage regulator (VR) with digital control, enabling efficient and adaptive power delivery that optimizes the performance of automotive HPC systems. Furthermore, MPS’s Intelli-Phase^TM DrMOS technology integrates the internal power MOSFETs and gate drivers into one package. Compared to discrete MOSFET solutions, Intelli-Phase^TM DrMOS achieves improved thermal performance and reliability, faster switching speeds, and higher power density.
