Other Parts Discussed in Thread: TEST is there an article about how how to select Coupled inductor? why L1 is 5.5mh，why L2 is 20mH. Now I want to Let the 4-level EFT decay below 10V, or below 0.5V, how to choose the common mode inductor? Is it possible to…
Eric,
This design is somewhat close: www.ti.com/.../TIDA-00702

Hey Scott, Thanks for your interest in TI! We have a reference that is very close to your specifications, we recommend basing a design off of this: www.ti.com/.../TIDA-00702 Use that design along with this app note to help debug any issues, should they…
Part Number: UCC28740 Other Parts Discussed in Thread: TIDA-00702 , Hello black magic wizards.
I have seen a lot of application notes concerning layout guidelines for switch mode power supplies. Most of them based on a 2 layers PCB stackup.
In our design…
Guifre,
First of all, for that power level (48 W), the original transformer inductance of 1.57 mH does not sound correct - that's far too high for such a high power level. In fact, even the value of 560 uH that you actually used sounds too high. Did…
