Hi to all,
Just wondered if anyone knows if I can drive a 2N6796 FET directly from the PWM output of a PIC?
I wondered because I only have experience in driving normal transistors where the gain is important, and have never used a FET as a driver before.
The FET will be switching 20v at 350mA (a string of 1w leds) and I can't figure out the FET datasheet.
Is there a relationship between gate current/voltage with gain on FETs or is it just on or off?
Thanks for looking..........Al
