Hello,

I am not sure what the marking's should like. I will try to see if I can get you in contact with the right team to look into this for you?

Hello,

I asked my colleagues about this issue and they provided the following information.

This part was designed in 1999, right around the time Unitrode was acquired by TI, so it's not unusual for there to be no TI logo.

However, if there is question as to whether the parts are genuine, you can fill out this form and follow the instructions: https://www.ti.com/lit/pdf/ssdl004
