Hi. Im glad to be here. I have a question about UCC2895. I want to work with UCC2895 but before I wanted to try by simulating it. I downloaded your pspice transient model and simulated in pspice like below.
As in the seen in second image, I calculated soft-start time tSS= ((22*10^-9 * 3.6 * 69800) / 3 ) = 1.84272 ms by looking from datasheet. And I assumed calculation is true. In simulation I obtained these ;
In 3. and 4. image about to EAOUT and SS pins in 0.5V so pwm output is open .
And 5. and 6. images about to simulation in 1.8 ms .
So I realized, when ss time in 1.84, Vout is 3V that is wanted. So I wonder, if my ss time is 5ms, Will Vout be 3V in 5th ms?
And how can I reduce pwm opening time? So how can I down EAOUT's 0.5V time?
Forgive me for my poor English. Thanks in advance
