Hi, The Lab power supply was presented at EEVblog #224 - Lab Power Supply Design - Part 1, Part 2 and Part 3 A link is below
He went much further on with this power supply, adding a micro and LCD display etc. but I just need the basics, although it would be nice to have the whole design, but my c coding is poor to say the least, so the basics is just fine.
My dream list is as follows:
Battery powered by (4) 3.7V 2500mAH 18650 cells.
Constant current and constant voltage
Variable from “0” to 10-12V output.
Variable current limit max 1AMP
Separate meter for current and voltage
Indicator when current limit reached
Automatic Battery low level cutoff (So as not to damage the Li-Po batteries)
I'm trying to reduce the Schematic, and will post when done.
Thanks all
