I've built a pwm controller with a mosfet as the power device...It would appear that my gate drive voltage is insufficient to saturate the mosfet...this is leading to becoming a little too warm for comfort...
Most pwm circuits I've come across drive the gate direct, presumably with no issue!
Supply rail voltage for the circuit is currently 12v with a view to increasing to 15v if need be...
Is there a discrete gate drive circuit I could use to aid driving the mosfet or do I have to go the commercial route? (dont really want to do that if I can help)
Offers of advice appreciated...
