can a power mosfet driver be used 'standalone'?
I found this on the datasheet for your MOSFET driver. I would suggest NOT using this IC to directly drive a transformer. If you do you must use series capacitor, polypropylene 100 nF rated for 50 volts, to block any DC currents. It might work ok, but no serious engineer would back up that design.


  Analog input voltage (INA, INB) –0.3 to VDD + 0.3 V not to exceed 16 V
  
  Output body diode DC current (OUTA, OUTB) 0.2 A OUT_DC
  
  Output current (OUTA, OUTB) DC 0.2 A
  
  Output current (OUTA, OUTB) Pulsed (0.5 µs) 4.5 A
  
  Output voltage (OUTA, OUTB) 16 V
