7.3.6 Output Short-to-Ground Protection

The TPS61099x starts to limit the switch current to 200mA when the output voltage is below 1.6V. If short-to-ground condition occurs, switch current is limited at 200mA. After the short circuit is released, the TPS61099x goes back to soft start again and regulates the output voltage.
