7.3.3.1 Slew Rate and Inrush Current Control (dVdt)

The inrush current during turn on is directly proportional to the load capacitance and rising slew rate.

Equation 3. IINRUSH  = COUT × SRON

TPS25961 provides a controlled turn on at a fixed slew rate (SRON) which helps to minimize the inrush current.
