Part Number:TPS62260
Dear Sir,
I need to suppy +3.3V external power on TPS62260's output because of MCU firmware update as below.
Is it possible? Does this external power supply damage TPS62260's internal circuit?
In terms of FB pin it would be OK because a small leak current like 4uA. I think it can not damage an internal circuit from the leak current point of view.
How about internal High side FET from the inrush current of view?
