Hi Team,
Could you pls check whether TPS259260 can support 12V/3.5A when the top case temperature is 80℃? Can you provide a curve of the maximum continuous current as a function of board temperature or ambient temperature? Thanks!

Hi Hailiang,
Tj= TA + I*I*RDSON*RQJA
Tj = 80+28 = 108
108<125C so this should be fine. I am assuming datasheet RQJA. They can lower RQJA by having more copper on board and proper layout.
