Maybe also worth to mention: Capacitive coupling of the driver to the gate will reduce
the peak voltage at the gate by half (assuming 50% duty cycle).
The IC driver voltage should be at least 12V in order to ensure
proper switching of the MOSFET.
If you use a transformer (as suggested by Stefan) one can fiddle with
the transformer ratio to get the proper voltage at the gate.

Forgot to mention, although I hope it is more than self-evident to readers here, the diode is orientated so it points 'upwards'; allowing a positive drive voltage to appear on the gate and clamping the negative to ground.
