Part Number: UCC28811 Other Parts Discussed in Thread: UCC28810 , TPS40211 Hello, first please forgive me to ask this novice question because I'm very much a rookie at power supply designs. 2nd please understand that I tried to tag the reference design…
Other Parts Discussed in Thread: UCC28811 , LM3447 Dear Sir ,
How are you? I hope you are good also your work .
we working on design street light (100 W) using (UCC28811) but we don't know How to design transformer for it .
so please if you have document…
Dear Sir ,
How are you? I hope you are good .
Thanks a lot for your fast response . we design a lot of transformer before but it was for small power & the data sheet of the IC's we were use describe How to design the transformer very well . this time…
Part Number: UCC28810 Other Parts Discussed in Thread: UCC28811 , UCC28050 Hello, My customer is looking for a LED lighting controller and found UCC28810/1 on TI.com. Can customer design their circuits using either UCC28810 or UCC28811 to meet the following…

Other Parts Discussed in Thread: UCC28811 Hello,
I designed a single stage PFC LED-driver with a UCC28811. I found that the input current has jumps around the zero crossing. I zoomed in on this in the below image.
I found that these jumps are caused by…
Other Parts Discussed in Thread: UCC28811 Hello,
I have made a flyback design with a UCC28811. The design is based on the SLVR574 reference design. The MOSFET controlled by the UCC28811 directly charges the transformer.
I added a dimming option to the…
