SLVSE57C June 2017 – April 2018 TPS2595
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 9.
For TPS2592xx device, the inrush current is determined as shown in Equation 8.
Power dissipation during start-up is shown in Equation 9.
Equation 9 assumes that load does not draw any current until the output voltage has reached its final value.
