how to get 0-90% duty cycle?
hello everyone
right now i am designing a PWM generator using SG3524N. SG3524N has two outputs with 45% duty cycle each output. I am using pin 9 as input. How to get 0-90% duty cycle? thx before
Thanks for the asnwer.
the input is on pin 9, my bad. I was try use error amp (pin 1) as feedback and pin 2 as input but the result is same as input on pin 9. If this IC can't give proportioniality, what IC I should use then?
This PWM generator is part of closed loop DC Motor Control system...
i am using IC SG3524N to generate PWM signal. The problem is how to make duty cycle proportional to voltage input (pin 9 Voltage) ?
here is my circuit. In this circuit, the duty cycle isn't proportional to voltage input.
thanks
regards
