Other Parts Discussed in Thread: PMP30631, , PMP, TL431
Dir Sir/Madam,
I have successfully simulated the design on the kit .
Now I want to change the design to output 5V ~ 6A.
Simple iteration of the ratios reported in the PMP30631 kit result in actual turns of Np=80 : Ns=20 : Na = 14.
Please let me know what is the best wire ratio I should use for the design.
I tried to simulate the number of turns Np=80 : Ns=5 : Na = 14.
Hower, ripple output is very high.
I send the calculation on the PMP30631 kit & for the part I calculate for 5V output.
Please help me with the issue.
I attached the file as below !
