HelloI would like to measure the efficiency of the EVALZ-1-ADP5090. For this I use the keysight b2901a. I use the first channel for VIN, the second for SYS. I have chosen the following settings. I_IN=0,1A to 0,001A, V_IN_compliance=2V, Vsys=3,5V and I_out_comp= -0,1A. Now I have the problem that there is only 0.245V at the input and that the MPPT tracking of the OCV does not work. Where do I have a thinking error? Or is it possible that the EVAL board is damaged? Thank you!
This ist was happend.
You can set channel1 as current source like 10mA and set the voltage limit lower than 3.3V or else it may damage the ADP5090.
also set the channel2 as voltage source like 3V and connect to SYS and BAT and monitor the current.
please guarantee to connect RDIV to MPPT of J3.
Is a current at the input of 100mA to much for the ADP5090? The last time the Keysight display at Channel 1 turns yellow/orange. I think that mean that the source reachs a maximum?
