8.3.9 Output Short-to-Ground Protection

The TPS61033 starts to limit the output current when the output voltage is below 1.8 V. The lower the output voltage reaches, the smaller the output current is. When the VOUT pin is short to ground, and the output voltage becomes less than 0.4 V, the output current is limited to approximately 330 mA. Once the short circuit is released, the TPS61033 goes through the soft start-up again to the regulated output voltage.
