Other Parts Discussed in Thread: TPS2546
Dear TI,
I have an EVM for the TPS2546. I came across what I think is an error in the EVM design.
It is about jumper JP1 that needs to be moved in between VIN and VBUS. Now you can apply auxiliary power to the board that is in parallel with the voltage supplied by the HOST.
The quick fix is to remove the JP1 jumper and feed the aux power through TP3.
Regards,
Roland
