SLVSET3D March 2020 – October 2020 TPS63900
The device has a inbuilt short circuit protection function to limit the current through Q1. The maximum current that flows is limited by the peak current limit. The output voltage decreases if the load is higher than the peak current limit. If the output voltage falls below 1.25 typically, the short circuit protection is activated. With short circuit protection activated the input current is limited to 26 mA on average.
The device automatically restarts to normal operation after the short condition is removed.
