Inquire TI Buck converter or controller and have CC/CV function

Hi Sir,

(Buck spec required: Vin:12V or 5V, Vout: 1V to 2.75V, Iout: 2A)

May I learn from you does TI have Buck converter or controller which integrated the CC/CV function in the chip?

If yes, please kindly recommend the P/N.

If not, does TI have Buck converter or controller reference design which have CC/CV external reference circuit?

Thank you for your kindly help.
