I'm DFAE. I have a question about EN pin of LTC2928.
How can I do when the output current of EN pin is not enough? Can I pull up EN pin by VCC(3.3V) or other voltage?
Yes, you can pull up the enable pin to another supply.
a sample of this is implemented on the data sheet reference schematics of LTC2928
What are you trying to drive with the EN pin? A schematic would be helpful.
Usually this pin is connected to the gate of a FET or the enable/shutdown pin of a voltage regulator; a high impedance…
