A Single-Stage, Single-Inductor, 6-Input 9-Output Multi-Modal Energy Harvesting Power Management IC for 100µW-120MW Battery-Powered IoT Edge Nodes

摘要

A 25MHz switching, event driven, 6-input and 9-output single inductor Energy-Harvesting PMIC (EHPMIC) with multi-modal harvesting capability from DC & AC sources delivers up to 120mW with a peak efficiency of 81.7% and only 120μW control power overhead. The high-frequency, high-bandwidth design optimally trades off EHPMIC conversion efficiency with inductor/capacitor size & transient response speed to enable the fast power state transitions demanded by the SoC in a compact IoT edge node, thus minimizing the overall platform size & energy consumption.
