Q: TPS65072 - Exposed Thermal Pad location by 10449

The TPS65072 exposed thermal pad appears to be centered in the Mechanical Data page of the datasheet.  The Thermal Pad Mechanical Data page shows that the pad is off center.  Which is correct?


A: Re: TPS65073 - Exposed Thermal Pad location by 10449

The package Mechanical Data drawing is not dimensioned, so it can not be used to understand or define the thermal pad.  Thermal Pad Mechanical Data drawing is dimensioned and is intended to show the thermal pad dimensions and location.

Please note that the TPS65070, TPS65072, and TPS65073 do not have a "PowerPAD".  These packages have and "Exposed Thermal Pad".  Refer to the mechanical drawings to determine if an IC has a PowerPAD or an Exposed Thermal Pad.  Please refer to the datasheet pin descriptions and mechanical drawings on how to treat either the PowerPAD or Exposed Thermal Pad for a specific IC.
