A:Ok what voltages can you get on vcc and vpp, what sort of range.. 0..25V and 0..5V???
And what Current?
Do you think it would work fine from 5V from USB?
If so your idea is good...
On the LPC2388 the ARM CPU we only have one DAC, so we would need an external DAC IC for your PSU to work.
Also in you PSU design what about pin 4 on the MC34063? I thought pin 4 was GND and pin 6 was VCC?????

U_hi/U_lo are just test pads on the board.
And Header 3 is just a 2 way jumper block.
