Part Number: UCC256403
Other Parts Discussed in Thread: UCC28951, UCC28950

Hi,

The customer has a demand for 1200W DC/DC power supply. The main requirements are as follows:
Please confirm whether TI has any relevant plans.

1. Input DC: 80-120V.
2. Output DC: 58V / 24A.
3. Input to output: isolation. Strengthen insulation. Comply with IEC62368.
4. Efficiency:> 97%.
5. Volume: small volume.
6. Waterproof and dustproof grade: IP67.

Can UCC25640X meet this requirement? Or there are other solutions I can recommend, thank you

    Hi Rock,

    Based on your input/output requirements, I would suggest taking a look at phase shifted full bridge. This topology would be better equipped to meet your efficiency target at the input range and output power of your spec compared to half bridge LLC. Take a look at UCC28950 or UCC28951.

    Best Regards,

    Ben Lough
