Generate 2 PWM signals with 90 degree phase shift

Postby jeard16 » Tue May 15, 2018 1:14 am

Hi,
I need to generate two PWM signals with 90 degree phase shift at 20KHz and adjustable duty cycle for controlling a switching power supply. I have looked in to this matter but wasn't able to figure it out. Can anyone advise what is the best way to do that?

ThanX in advance.
