Hi Glenn,
Thank you so much for pointing out these errors! Sometimes things slip through the editing process. We will get them corrected and update the document.
thank you,

Hi Amal,
C1 could be moved to the other side of the bridge if desired. Additionally L1 could be moved to the other side of the bridge. This is just how the designers of TIDA-010047 chose to design the differential mode input filtering.
In either location…
Hi,
The TPS25730 can be used for an easy way to implement USB-C PD UFP. https://www.ti.com/product/TPS25730
Please see PMP41100 as an example of a similar application. https://www.ti.com/tool/PMP41100

Hi,
Check out this Power Supply Design Seminar topic on "Flyback transformer design considerations of efficiency and EMI" : https://ti.com/lit/slup338
On page 17, there is a section on "How to estimate and minimize leakage inductance" with a…
For a lighting application that requires PFC, UCC28811 is recommended. PMP22538 is an example of a 60W PFC-flyback using UCC28811, but output voltage is not exactly what you are asking for.
Hi Vipin,
I think what is happening here is that the UCC28730 is in CC regulation at startup because the converter must supply the 1A load plus current to charge the output caps. This causes the startup time to be longer, and there is not enough capacitance…
