Hello Manuel,

Please verify this part number, as I am not finding a reference to it, not even in the online suppliers. Where did you come across this part number?

Dear Leonard,

i got the number from our distributor when i ordered the PWM controller UCC2570N.

He said that he bougth a remaining stock from UCC81331 and it should be the same as UCC2570N.

Please see the attached text below.

The full part number callout is UCC2570N/81331. The part is marked: UCC81331

TI says – this was old Custom Device (NOT a true custom) for one of their customers.

This Part should perform exactly the same (if not better) than the UCC2570N. It is believed this part was created initially to give their customer

Extended temp limits and Special branding.

Best regards

Manuel

Hello Manuel,

The UCC81331 is an obsolete custom marked version of the UCC2570N; the UCC2570N datasheet is attached, please note the bold heading on page 1:

Not Recommended for New Design.

Also refer to this E2E thread: https://e2e.ti.com/support/power_management/isolated_controllers/f/188/t/162629?tisearch=e2e-sitesearch&keymatch=%20user:76405 .

Please also note that it may be likely the UCC81331 was obtained from an unauthorized source, and may even be counterfeit, and recommend these NOT be used in a new design. Instead, please select an appropriate device for your new design from these similar, functionally equivalent parts from this list: www.ti.com/sitesearch/docs/universalsearch.tsp?searchTerm=ucc2570n#linkId=8&src=top .
