TPS65233-1: Junction Temperature Spec

Part Number: TPS65233-1

Table 6.3 Recommended Operating Conditions specs the Junction Temperature range from -40 to 85 C, but calls it Ta. Does the table mean Ta (ambient temperature) or Tj (junction temperature?

    It means ambient air temperature.  If you look at the electrical specifications table top-line, you will see that the electrical specifications table covers junction temperatures from -40C° to +125°C.

    TI recommends using the part with an air temperature between -40°C and 85°C and a junction temperature between -40°C and 125°C.
