I'm looking for ways to drive an IRF730B or similar from a low-voltage AVR - it must be very simply and cheap (its to drive a boost converter).
I was going to drive the gate directly from the PWM, with a series 200ohm resistor and a diode from the gate to ground (C to gate, A to GND). This would work fine for logic-level FETS, but I need to switch peaks of 250V DC at about 50kHz.
I'd prefer not to use an extra chip like the Maxim FET drivers, so was looking for ideas... The IRL630S looks a possibility... using an ATMega16L
