Power Dissipation
The power dissipation in the TPS55386 is from FET conduction losses, switching losses and regulator losses.
Conduction losses are estimated by:
The switching losses are estimated by:
The regulator losses are estimated by:
Total power dissipation in the device is the sum of conduction and switching losses for both channels plus
regulator losses, and are estimated to total 1.2 W.
