Tool/software:
We are going to use UCC28910 to design a buck converter with 24V output and 0.4A. There is an application note for UCC28910 operation scheme in Buck…
Part Number: UCC28910 Other Parts Discussed in Thread: PMP41106 , Tool/software: I'm developing a 25.2V, 20A charger using the PMP41106 reference design. The design includes a PFC, LLC, and flyback stage. I have developed a schematic and PCB, and I would…
Part Number: UCC28910 Other Parts Discussed in Thread: UCC28881 , UCC28750 , UCC28911 Tool/software: Hi,
Q1. Is it generally not recommended to use UCC28910 as a buck converter? The operating environment is as follows. -Input: DC 200V -Output: DC 18V…
Part Number: UCC28910 Tool/software: Dear Team,
We are currently working on a flyback converter design using one of TI’s flyback controller ICs. We have received the transformer (T2) from our magnetic component manufacturer, and it meets our electrical…
Part Number: UCC28910 Tool/software: Hello TI Support Team,
We have designed a flyback converter using the UCC28910 , powered by a 390VDC input from a half-bridge PFC stage .
When we power ON the system:
The secondary voltage ramps up from 0V…
Part Number: UCC28910 Other Parts Discussed in Thread: UCC28911 Tool/software: Hello,
I’m designing a flyback converter using the UCC28910 . As per the transformer connections shown in schematic, I had a custom transformer built by a manufacturer. I…
Part Number: UCC28910 Tool/software: Thank you for your reply!
But I would like to know how this resistor affect the converter operation.
Is this because it affects the timing of the Vs pin
Part Number: UCC28910 Tool/software: Before I add snubber and fitering, I swapped IC (UCC28910) between good and bad board. The same issue followed with IC, which mean if move IC (UCC28910) from the none-working board to a working board, the working board…
Part Number: UCC28910 Other Parts Discussed in Thread: PMP8590 Tool/software: Thank you for your support.
Please see my answers below.
1) what did you change besides the transformer?
My design is based on the reference design PMP8590. The only change…
