Hi,
a question to Hans:
What if the PCB #2 SMPS card is not present (or is faulty)? So the ADC 3V3 signal line would be open.
Does the FW algorithm let the 3V3 linear regulator work for VDD instead?
And does the LDO in this case withstand the constant dissipation?
In other words, if one decides to operate the 3V3 rail from a linear regulator or to just troubleshoot using this option (without the PCB #2), would it be enough to ground the ADC 3V3 line on the connector?
