Hi Ulrich,
sorry for the late reponse. We have replaced several components, such as the driver IC U2 and Q5 and almost all active devices. but no success so far. We still have not replaced R19, R21, R23 and Q4. We will do that too and I'll get back to…
Part Number: UCC29910A Other Parts Discussed in Thread: UCC28070A , , UCC28019A Tool/software: Hello-
I'd like to implement a Buck PFC to convert 3-phase AC power (either 208 or 480 in separate designs) to ~200 Vdc at maximum of just over 2kW. According…

Is there any controller for BUCK-BOOST PFC Topology?
I think it could solve the issue of AC valley for PF.
Thanks.
Part Number: UCC29910A Other Parts Discussed in Thread: UCC29910 Tool/software: Hi,
is there any BoM for the UCC29910AEVM-730 reference design? What is the L4 Transformer for instance?
With regards
Part Number: UCC29910A Tool/software: Dears,
My customer want to use UCC29910A for 500-900VDC input,320VDC/500W/1.6A Buck output.The reference circuit of UCC29910A 85V output evaluation board has an output terminal voltage sampling circuit, which uses…
Part Number: UCC29910A Hi,
I would like to design a PFC converter in buck configuration.
I found the UCC29910A, and I would like to know if can I use it with an input frequency range goes from 400Hz to 800Hz Vin=115VAC ?
Thank you for your reply.
A+
Part Number: UCC29910A Other Parts Discussed in Thread: UCC25600 , , UCC29910 , UCC256404 Hi TI expert,
The new project design is under the AC 400V system and is needed to provide a 24V @10A output. So in my opinion, the ac input voltage will be higher than…
Part Number: UCC29910A I know, I know, this topic has been discussed before, but I wanted to share some information and possibly get some information back.
I'm currently running this at 120VAC and keeping the 84VDC output, starting with the Eval Board…
Part Number: UCC29910A I was wondering if the UCC29910A can be used for 3 phase operation with a standard bridge. Assuming for now that the voltage is within the operating range, will having the AC waveform 120 degrees out of phase instead of 180 degrees…
