Different asset settings give different optimal harvesting modalities, so the MHM product uses a separate module to house the harvesting transducer for in-field reconfigurability. A single-inductor multiple-output (SIMO) regulator transfers energy from VCAP to three VDDs, including an adjustable rail (VDDADJ) for dynamic voltage and frequency scaling (DVFS) across different process, temperature, and operating modes.
