Part Number: UCC28630
Other Parts Discussed in Thread: UCC256301

Hi, team.

I would like to promote to a 200 W isolated power supply for communication base stations with TI's solution.

I imagine the following circuit using UCC28630, but can you consider used in practice?

If the following circuit is not realistic, is the LLC Circuit better?

(For example: UCC256301 etc...)

Best regards.

Hello Pokkun,

Thank you for your interest in TI portfolio.
Can I ask if you have more elaborate specifications: like the input/output voltages, switching frequency, etc.
This information will help me understand your application before making any suggestions.

Regards,
Sonal

Hi, Sonal-san.

Input Voltage：-48V

Output Voltage：12V

We do not discuss with customers about Frequency.

However, I think that it is better to move at a frequency as high as possible,

because the customer want to design it with a small size and high efficiency.

Best regards,

Dear Pokkun,

Thanks for your question on TI E2E website.
I have one more question on your customer design.
Is 200W continuous or temporary for short time peak power?
If peak power how long is this peak power event for and what is max continuous power?

Best Regards
Kevin

⇒Continuous.

Dear Pokkun-san,

Thanks for your reply.

If the circuit is 200W for continuous power, you can refer to TIDA-00367.

But I think if you need higher efficiency, LLC will be a good idea.

Best Rgards
