I need somthing to convert an input voltage of between 3.6 and 7 volts
up to 50 volts in 5v steps, and it has to fit in 2x2cm square(or
smaller). The project will use a uController so i will have a PWM

 Have been looking at the article in SC re converting AT power supplies
to 13.8V bench supply. Has anyone done this with an ATX supply? In
addition to being able to get 13.8V @ 20A, I'd also like to modify one
to give around 28V @ whatever current it can produce - preferrably ...

I was wondering if anyone knows how the N divider worked on the
Motorola PLL Frequency Synth MC145151-2. It has pins N0-N13. I am
