UC3846: Duty ratio of PWM to UC3846
In reply to Benjamin Lough: Go to Support forums. In reply to Benjamin Lough:. Nov 15, 7: Hi Jenny, Duty cycle is determined by comparing the output of the error amplifier COMP pin and the ramp signal derived from the current sense pins.

You can calculate the dead time from equation 2 on page 12 of the datasheet: Do you have another question? Nov 8, 1: This thread has been locked.

Duty cycle is determined by comparing the output of the error amplifier COMP pin and the ramp signal derived from the current sense pins. If it is not controlled by feet 5by which parameter adjusting?
Hi Jenny, Thank you for your interest in UC But currently I found that UC has a frame-throwing phenomenon at work. HI Ben Lough, Thanks for your reply. The newly created question will be automatically linked to this question.
Menu Search through millions of questions and answers User. Best Regards, Ben Lough. Nov 13, 3: I would suggest adding a current sense resistor such as what is shown on page 11 of the datasheet: And I want to askdoes UC adjust the duty ratio by adjusting the setting voltage of the feet 5?
And lastly I want to know how to adjust the output of voltage by adjusting the duty ratio?
