Very simple for someone who knows what they are doing!

Based on this circuit here:
  [obscured]  /playground/Main/RegulatedPositiveVoltageBooster

I want someone to add to this this booster circuit so that I can square wave "chop" the output of this via another PWM from the Arduino. Around 1kHz or so.

Of course the Aout feedback will be chopped as well so this would have to be taken into account.

The frequency of the chop and the amount of boost will be variable via pots.

All I want is the circuit diagram. I can do the rest myself. Some 20 years ago I trained as an electronics engineer, but went into a different industry, so I'm preeeety rusty.

This is a dead easy job for someone.
