9.2.3.3.1 Case 1: Start-Up Without Load. Only Output Capacitance COUT Draws Current
During start-up, as the output capacitor charges, the voltage drop as well as the power dissipated across the internal FET decreases. The average power dissipated in the device during start-up is calculated using Equation 11.
For TPS2596xx device, the inrush current is determined as shown in Equation 10.
Equation 10. 
Power dissipation during start-up is shown in Equation 11.
Equation 11. 
Equation 11 assumes that load does not draw any current until the output voltage has reached its final value.
