UCC28061: The input voltage range and output voltage range

Are you looking for a PFC controller or a boost controller? 

UCC28061 is a boost PFC controller and it looks to me that you are looking for a boost controller for DC/DC applications.

I need both PFC controller and boost controller.

And wanna ask if input voltage: 20V ; output voltage: 50V  ,operating in CCM mode could it be possible?

And also need a interleaving boost controller IC.

UCC28061 is an interleaved boost PFC controller. It is CrCM mode though. Newer family is UCC28065

If you need interleaved CCM PFC, we have UCC28070.

Thank you!

Do TI have boost interleaved boost controller?

I will assign this request to the right team to handle.

Thanks a lot

Hi,

our engineer is out of office.

He will reply tomorrow.

Hello,

Sorry for the long delay. This thread must have slipped below our radar after getting re-assigned.

If you are looking for an interleaved boost controller, I can recommend LM5122.
https://www.ti.com/product/LM5122

This devices matches your given input/output voltages specs and is optimized for multi phase designs.

Please let me know if you have any questions on this device.

Best regards,
Niklas

Hello,

Do TI have the typical circuit that I can use for LM5122 ?

Or just use thissimplified diagram to design my project?

Hello,

Yes, we have an EVM board which shows a typical LM5122 application with two phases:

A second EVM with only one phase is available as well on the product page.

Hello, 

So if I want a normal boost converter,  just use the simplified diagram to design my project?

Best 

Thank you very much!

Have a great day.
