Hi,
When we worked at buck mode ,we have noticed that change in the PWM does not change the actual PWM that trigger the gate, there for the d-s is triggerd at ~50%.
i found this thread, which ask Ram the same question but he did not answer it.
can you please clarify it ?
in the photo you can see that PWM trigger of 10% duty cycle correspond to ~50% d-s triggering
yellow and green = 10% duty cycle from the dsp
blue and orange = drain source of q6,q7
Thanks
Michael
