Hi,
At 45V, 20A its a 900W supply, if the output voltage has to be variable between 4.4V to 45V then I recommend you use a two stage approach.
A single phase PFC, using the UCC28180, TI has a 900W design TIDA-00443 which could be used with a phase…

I would like to know part number of isolated gate-driver for like a Typical application by datasheet.
If there is no recommended isolated gate-driver, please…
Hi Yusuke,
The TPS40210 may work and the following reference design needs similar currents and voltages as what they need. However a higher voltage MOSFET would be needed to support the 240 V output.

For the bigger MOSFET…
Hello Tobias,
Both parts used for L3 and T1 are custom magnetics.
L3 is a pretty simple PFC toroidal inductor, without any auxiliary winding, so it should not be difficult to find a similar one on the WEB.
T1 is more specifically designed for this…
Рисунок 9 sluaao8.pdf It shows under what loads which controller is best used. I have a question. Why doesn't the UCC28065 on one phase work with the same efficiency as the UCC28056 on a load less than 200 W? Thank you. I'm sorry, but I can't create a…
Ben-san,
UCC28056 have Brown -in AC85V fix but do not have Brown -out . Is this right?
If Customer want "Like Brown-out" at AC70V, not depending on secondary load.
Additional opAmp cct., such as "UCC28180- LMxxxx NDA cct" is required?
Your recommended…

I Want to design a dc source, which output spec is DC 0~30V/10A/300W, 3 Set
What kind of parts do you suggestion?
thanks
Hi,
which topology do you want to use for PFC?
For analog soluation TI have UCC2818/UCC28180 for single Phase CCM PFC, and UCC28070A for two phases CCM interleaved PFC, and UCC28063 for two phased Transient mode interleaved PFC.
And also has digital…
