One of my customer is interested in ADP5090 performance but the question is their max solar power is around 1W and ADP5090 is only around 300mW, so the customer asked me that is it possible that parallel multi ADP5090 to increase the power? if yes, they can make the number of solar panels divide into half and half and then, they could use two ADP5090 to achieve their goal.
ADP5090 definitely can operate in parallel. But two ADP5090 may not extract 1W power from the solar panel.
please consider the the Rdson between BAT and SYS because there is a voltage droop during high system power.
