Energy Harvesting

Asahi Kasei Microdevices Corporation (AKM) step-up DC-DC converters can start up a step-up circuit from a small input voltage.

You can choose the product according to the performance of the power generation element used.

* Input voltage [V] :

The input voltage when the energy harvesting device is connected to the converter. (not open circuit voltage of the energy harvesting device)

* Minimum inpit volatge to reach to VDETH2 [V] (Referance value) :

The input voltage when the energy harvesting device is connected to the converter. (not open circuit voltage of the energy harvesting device)
These voltage is reference data from AKM evaluation board, not product specifications.
Refer to "downolad” to check the AKM evaluation boards in product page.

Check with the power simulator

This simulator can calculate the power available with any generating element and AKM's step-up DC-DC converter. It can be used to estimate the environmental energy collection time when considering a system.
