Part Number: PMP20541 Other Parts Discussed in Thread: UCC2897A , Hi TI Friends
From the datasheet, UCC2897A is a fixed frequency with a typical 250kHz and the max fsw is 270kHz, but there is a "fsw=300kHz" in PMP20541 schematic.
Is this a error or…
Part Number: PMP20541 Hi Team,
I can not find the datasheet of ATS-1410R-WNC through Google, could TI provide this datasheet?
Also, I can'f find this part number in Atech OEM Inc's webside, maybe this one is no longer exist, could TI provide the alternate…
Hello,
I confirmed with a colleague that we do not have a test report for this design. The TI TIDA 050023 is the optimized solution:
Please note, as in my last message, that these are different designs. This design does not contain the FET you…
Hello, unfortunately you cannot change the output voltage. The transformer cannot handle 48W. Take a look at PMP20541. This design has a 12V/4A output.
Thanks,

Hi Darwin,
Thanks your information & suggestion.
Would you kindly provide PMP20541 schematic file for reference, such as Altium/ Orcad?
Thanks your help.

Hello Andy,
The pdf you attached shows the PMP20541 reference design. This uses the UCC2897A in a flyback application with the AUX output driving a synchronous FET on the secondary. This synchronous FET is also the main flyback rectifier. So the answers…
