Hi all,

I'm trying to put together a stepper motor driver board using L297/8's.

The stepper motors I'm using are rated bipolar 4.2V/phase at 1.2A/phase.

I wanted to use an old PC power supply, as it can nicely do 5V at upto =
22A ready done.

But what's the best way to get 4.2V from 5V at about 3A per driver board =
and be able to run it with a L298???
I've tried looking up voltage regs at 4.2V with no luck, or zeners...
Would a simple series resistor or voltage divider do the job... but at =
15W could they handle it???

Anyone any ideas...


Cheers all

Kev/.
