In BF-548 EZ-Kit Lite, Pg-17 2.5V for DDR and 5V for USB are generated from ADP1823, 2.5V is tracking VREG5, whereas 5V USB is not tracking anything.
Why is it done so as blackfin does not have any power sequencing requirement, can i use separate switcher to generate 2.5V for DDR and DDR Controller?
I have moved this question from the Processors and DSP community to the Blackfin Processors community. Please continue the discussion here.
I didn't understand your point. What is the problem in using ADP123 to generate these voltages.
