I have two questions about ADP5091. Please take care of this case.
1. Question about MPPT value.
Please take a look at the attachment. I set the MPPT to 0.5 (10Mohm + 10Mohm resistor divider) but could not get 0.5 actually.
- How come I could not get MPPT=0.5? Is it because too low internal resistance of TEG?
- How can I get as close to 0.5 as possible?
2. I'd like to measure ADP5091 efficiency without BAT.
I want to know Effi = REG OUT Output power/Input power from TEG. However ADP5091 seems to be disabled without a rechargeable battery at BAT pin. How can I measure the efficiency without BAT?
