With respect to the ADSP-21489 development board, I would like to run the 1.1V and 3.3V switching regulators from a 12 Volt supply rather than the 5V supply used in the original development board. Is there any reason why I can't do this ? Would I need to changed the output inductance/capacitance values ? Also could I run the switching regulators from an unregulated supply ?
