SLVSFZ1 December 2020 TPS27SA08-Q1
The DC current under maximum load power condition will be around 7.03 A. Power dissipation in the switch is calculated in Equation 3. RON is assumed to be 20 mΩ because this is the maximum specification. In practice, RON will be lower.
The maximum junction temperature rating for TPS27SA08-Q1 device is TJ = 150°C. Based on the above example calculation, the device temperature will stay below the maximum rating.
