Sorry if I didn't make myself clearer. I am designing a new board from scratch so I am using some of the ideas from the EZ board. I was toying with the idea of using a 24V center tapped transformer supply (plus regulators) to drive both the analog and digital sections instead of a 5 Volt regulated supply.
If I use a 12 Volt supply to drive the 1.1V and 3.3V switching regulators would I have to increase the value of the 2.5uH switching inductors ??
