New TechiTip added to our website for a 5p (GBP) or 10c (US) FPGA based charge pump power supply. You will find it hereIt's good for a bus switch power supply and for using N-Channel FETs in providing an above rail gate voltage application. We are using this circuit in the new board Tarfessock1 so you will all get to see the end results. It has a number of applications beyond this Techitip and we may do some follow ups if there is enough interest.
