Other Parts Discussed in Thread: TPS63900
I have been able to get TPS63900 provide reasonable output with my selection of the config resistors. The measured ICL is slightly off (shows 3 ma instead of the 2.5 ma from the datasheet) and
the output is 3.4xx rather than 3.400. That is not an issue for me.
I want to find out if I connect a higher voltage source (say 5V) to the Vout (designed to produce 3.4V) for a minute or so, does that cause any damage?
During the regular operation, that source will be disconnected. I have to do that in order to quickly charge a supercapacitor (EDLC) when the board is first powered.
