Part Number: UCC2897A Other Parts Discussed in Thread: PMP7499 , Tool/software: At present, the products based on PMP7499 output 12v5a work normally, and the new demand needs to modify the output voltage to 24V2.5A. How to modify the transformer coil and…
Part Number: UCC2897A Hello Teams,
I have some questions under URL's Design Calculator.

1. B32 are wrriten "Curent Transfer Turns Ration".
What should I write here ? Is it the current transfer of the chart…
Biswajit,
-Sorry for the delay. After doing some research on how to model the input impedance, I found the following resources:
a. Please, see below the Canonical model of a buck converter (similar to forward).
b. When calculating the input impedance…
Terry,
The specifications of RA7040 and PH0805 are different. The number of turns from primary to secondary are different and the primary inductance is different (see below). I recommend ordering RA7040 to follow the PMP9720 reference design.
RA7040-AL…

Hi,
I checked all changes since 2009 on UCC2897A and did not find a change record on the bond wire change so no associated PCN. If you can provide the evidence 2010 AU wire information, I can use that as a clue to try another time.
What is your concern…
