I have a customer interested in using the buck topology for this battery charger, which can reduce using 2 FETs instead of 4 to reduce PCB size. From looking at the datasheet topology, we may need to put a 0Ohm resistor or connect where Q4 would be to only use the buck topology. Do we have a schematic with only the buck configuration?
Additionally, our customer is interested in using WEBENCH to see to help design for the L, R, C selection. I couldn't find one for the BQ25731 device. Do we have any calculation tool for this? Otherwise, I would advise them to follow the "Application and Implementation" section of our datasheet.
