Other Parts Discussed in Thread: UCC29910A, UCC29910, TPS92074

Hi all..

I wanted to ask if there is a LTSPICE or PSPICE model available for UCC29910A IC? And if not  can you suggest any other IC for the same application? Or any other ic which can be used for power factor correction (pfc) using buck converter?

    You can use TPS92074 for PFC buck . It can give you power factor over 0.9. UCC29910 is not for lower power LED application.

    David:

    Thanks for your suggestion. But i need a ic which also have a ltspice or pspice model too so that before going for hardware i can simulate the circuit in any of these software. And i tried finding the same for TPS92074 i could not get one. So i request if you can suggest some ic which can be used for pfc buck and at the same time has a ltspice or pspice model.
