I need to shift a PWM signal (switching freq - 300kHz) from (0 to 5V) to (-50 to -45V). Output is going into an IR2011 gate driver. Available supplies are +/- 50V, +5V and GND.
I'm told I should be looking at using a PNP level shifting circuit, can anyone comment and elaborate as to what that is?
Thanks,
David.
