" summary

NOWI Energy presents a working PMIC for energy harvesting that claims configurable MPPT and an inductor-less DC-DC converter and is demonstrated with four small solar PV cells charging a supercap/battery. Test rig uses multimeters and current meters and shows a functioning PCB module delivering roughly 30–40 µA charging current in light and dropping to sub‑100 µA when covered. The build is real hardware and the measurements match the presented capability.
