3.3V 5V, 12V or 15V Switched PSU

This is the PCB for my switched PSU. It takes 40V in and can be made to produce 3.3V, 5V, 12V, 15V etc. With Pictures you loose a bit feeling of the actual size, so I put a TO247 transistor next to it – this is the smallest PCB I have made so far.

It is designed as a drop in replacement for linear regulators since I often need 2-4 PSU’s on a motor/PWM design. Regulating from 40V to 3.3V means you use a lot of Power. Will assmble a few of this for testing later.
