Hi all,
I am designing circuits and usually i am making solutions for things where other engeneers r not 100% successful.I will not act like a begginer here or try to "steal" the knowledge.I will be glad to share or help.This time i need help.I tryed many times to make as I said in title block of this post PWM which should work on max up to 1Mhz with fine regulation of duty cycle.I tryed with SG,TL and many other ICs and i couldnt get desired result.Last what i tryed was UC3843 and with current regulation i achieved 0,1% to 95% with basic schematic in its datasheet.Still i dont have good result couse it is not 1% to 99%.The thing is that i want to make this without any MCU and couse of that chalenge is bigger.There is IC which can do this its LTC6992-1 but the thing is that i want to make this not to buy some solution.If anyone can help or have something to suggest i will be glad to try.
Regards,
