Hi all,
Please would someone give some guidance as to which PNP transistor I should be looking for when switching PWM at 4MHz, ON signal is LOW (0V)
All the transistors I have found so far have rise times of 300 + ns, I need around the +/- 60 ns mark.
Background: I am going to drive a series of 3w LED's using a TLC5947, via a PNP transistor then an NPN MOSFET, then the LED.
Thanks
