OK, that's a limitation I have overseen. Thanks!

Hi

Also note that the nPM2100 is having a maximum input voltage limitation of 3.4V. So if you are planning to use it with your energy harvesting system, make sure your energy storage / rechargeable battery is within those limits.

I don't want to use the nPM2100 as charger, just as power regulator for VDD_GPIO. For the nPM2100 a combination of an solar charger and rechargeable battery (both other manufacturers) is pretty much the same as non-rechargeable batteries, which (hopefully) never gets drained.

Hi Achim

nPM2100 PMIC is not intended to be used with rechargeable batteries.

It is not a fit for nRF91 Series products.
nPM2100 PMIC is a boost regulator aim for non-rechargeable batteries.
1.8 V to 3.3 V output voltage with 150 mA Output current maximum.
0.8 V to 3.0 V in LDO mode with 50 mA Output current maximum.

Also, currently we don't have any PMIC in our portofolio which can support energy harvesting.
