Ghani Lawal- Making a circuit to automatically select the 3.3V power source:
- Buck converter as priority
- ***Input impedance of buck-boost converter's output pin will vary based on the design of the buck converter. It could range from very high (practically open) to low (due to passive paths or body diodes)
- Applying a 3V to the output of an unpowered buck-boost converter, i.e. a pre-biased condition can harm the IC unless it is explicitly designed to handle pre-biased conditions
- Testing circuits in LTspice to see what works
