17 Overcurrent Protection
For protection against load faults, the TPS84210 uses current limiting. The device is protected from overcurrent conditions by cycle-by-cycle current limiting and frequency foldback. During an overcurrent condition the output current is limited and the output voltage is reduced, as shown in Figure 26. When the overcurrent condition is removed, the output voltage returns to the established voltage, as shown in Figure 27.
