If uncle Bob hasn't the time to finish the solution, you may
want to have a look at the LT1076 from Linear. I use one in
a product to give out 6V @2A from around 8V to 35V. It doesn't
even heat up.

Hi Tjaart

Thanks for your reply. These parts are clearly the solution! The National
parts are even cheaper, however, I have attempted to source these things
locally and get the min quantity 2000 story. Mail order starts with $10 for
the part $8 P&H,  $5 Customs & excise fee $5 exchange and $1 tax! This
makes it impossible to do on the one off scale. Uncle Bob has been really
good at finding workable solutions for others, I'm sure he'll come through
for me, and I'm prepared to be patient.

Many Thanks and best wishes for the holidays!
