R3 & R4 should be bigger as they pass the feedback current.
Input ground an decoulping one should be separated and then only join a common point.
Input circuit is surrounded by output devices. I would prefer to keep it a bit apart.
On a fast glance.

I'm rather new around here so my apologies in advance for a possibly daft question.
Which software did you use for this PCB design? Everybody else, please chip in - is there such a thing as strongly preferred/standard package? Free?
Thanks, Mike

There is a free download called Design spark it has all the funtionality of
Easypc which I have bought for £350 and even beter components library
It was made in collaboration with RS components.

It was recentley advertised in Elektor magazine.

Being Free you may give it a go certanly you got notthing to loose.

Just gogle up Design spark.

Altrough not needed if you cook your own board it has output for gerber and such
That is the only standard one need for professional output/ functionality.

Pin spacing and track size and so on is al there

Massimo.
Can you translate mils to mm please.

I wasn't planning on etching at home. I'll get some made with proper solder resist and silkscreen.

Gate stoppers like R13 must be the closest possible to the mosfet gate...
