Part Number: UCC28712 Hi team,
Could you give me comment on following customer questions?
Q1. For package outline in the datasheet at 35p, the 7-pin is labeled as 8. This is SOIC(7), so should it be the 8 is labeled as 7? If so, could you correct…
Part Number: UCC28712 Other Parts Discussed in Thread: UCC28711 , UCC28704 Hello - we are designing a 200 to 1000VDC input, 24VDC, 0.625A output power supply and are looking at the UCC28712 flyback controller coupled with the Coilcraft WA8759-AL flyback…
Part Number: UCC28712 Other Parts Discussed in Thread: UCC28730 Dear sir ,
we want to design a buck converter using UCC28712 . The Input voltage range is (25-67.2V ) and output voltage is 10V and load is 100mA(max). when the input voltage is at its…
Part Number: UCC28712 Other Parts Discussed in Thread: UCC28710 , Hello,
We have designed buck converter based on the UCC28710 (but used UCC28712 instead due to unavailability of stock). Below is the schematic for the same.
Out of 4 boards, in 2…
Part Number: UCC28712 Hi, With the UCC2871x controllers, do you know if it’s possible to trick it into maintaining a minimum switching frequency of 33kHz rather than dropping back into frequency modulation at lighter loads?
Hi,
you have helped me a lot! Thanks.
Going through my calculations I see, that I must be hitting the constant current regulation level.
I will follow your suggestion to increase the turns ratio to something around 18.
I think I am beginning to…
Other Parts Discussed in Thread: UCC28910 , UCC28712 , UCC28700 I have successfully utilized primary side regulation in line voltage AC applications, but now have a requirement to support a 24VAC/DC system input. With respect to the transformer design…
Why there is this discussion?
There are so many questions in the forum related to the startup of UCC2870X or other TI PSR controllers/switchers. We know the anxiety when customer met startup issues. So we develop to try to aim customer on their issues…

Hi,
We are developing a flyback converter with 85-265Vrms 50Hz input to 12V, 1.5A output using the PSR IC UCC27812D. But during our tests we observed that the output is oscillating…
