Tool/software:
I want to use this converter to control a TEC module. I had no trouble doing that using the BOOSTXL-TECDRV connected to an ESP32.
I then designed a custom board with the TPS63810 integrated but with this board I cannot even see the device on the i2c bus. There is another different device on the same bus that I can see fine, if I connect the BoosterPack to the same bus, I can see it, but I cannot see the one that is on the custom board. I am attaching here the schematic and the PCB layout, they are heavily based on the BoosterPack's design but for some reason, it doesn't work. I cannot see the device on the i2c bus and Vout=Vin with Vin=3.3V.
I have tested 2 separate boards, same thing. I must have made a mistake somewhere but I cannot see it. Does anyone see anything wrong?
