Hello guys,

One of my customers is looking for TI load share controller for 3.3V, 5V, 12V, and 24V power line?

Could you please tell me the best matching device in load share devices (UC2902, UC2907 and UCC29002) for each power line?

Your reply would be much appreciated.

Best regards,

Kazuya.

Hello John,

Thank you very much for your reply.

But the minimum reccomended supply voltage is 4.575V. So I think UCC29002 can not be used for 3.3V power module.

Which device do you recommend for current sharing of 3.3V modules?

Is it UC2902?

If do you have any document for 3.3V current share with UCC29002, could you please share it?

Your reply would be helpful for the customer and me.

Thank you again and best regards,

Kazuya.
