HI Ben Lough, Thanks for your reply. Content on this site may contain or be subject to specific guidelines or limitations on use.
And I want to askdoes UC adjust the duty ratio by adjusting the setting voltage of the feet 5? Menu Search through millions of questions and answers User.
Duty cycle is determined by comparing the output of the error amplifier COMP pin and the ramp signal derived from the current sense pins. The product does not contain any of the restricted substances in concentrations and applications banned by uc3846b Directive, and for components, the product is capable of being worked on at the higher temperatures required uc33846n lead—free soldering The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: From Texas Instruments, a range of Pulse Width Modulation controllers and associated devices to suit a variety of applications and specifications.
If it is not controlled by feet 5uc8346n which parameter adjusting?

I an confusing how to resolve it?
When the open-loop occasion, the duty ratio can not be adjusted by feet 5. You can calculate the dead time from equation 2 on page 12 of the datasheet: In reply to Benjamin Lough: Thank you very much!

Nov 13, 6: Hi Ben Lough, Thanks for your help. But I still have two doubts about it. Could you provide some details?
RS Components Statement of conformity. 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.
But currently I found that UC has a frame-throwing phenomenon at work. This thread has been locked. Nov 15, 7: In reply to Jenny Lu Nov 8, 1: Are uc846n seeing this after adding the sense resistor?
