UC3867

Henry-liu,

What kind of support do you need? This is  a very old IC and there are more current ICs that have better support for resonant topology.

I have included one of the design Seminars for the older ICs as an attachment to this response. Hopefully it will provide some guidance.

Regards,

John

Hi John:

I'm a FAE of TI disty, one of the customer want develop a inverter, 12VDC input, 120VAC/100W output, they used TL494 and UC3525 in other projects, but the efficiency is not well.

Checked the UCC28250, the operate voltage range is not fit to 12VDC, and the customer need ZVS/ZCS, so the customer selected UC3867, but only datasheet on website, need more applicate circuit or reference design support.

Thanks a lot!

Henry-liu,

Take a look at the UCC25600 as a possible resonant topology converter controller.

There is more support for that part available.
