6.3.6 Overvoltage Protection

The TPS56623x has the overvoltage protection feature. When the output voltage becomes higher than 115% of the target voltage, the OVP is triggered. The output is discharged after a 32-µs wait time, and both the high-side and low-side MOSFET driver turn off. When the overvoltage condition is removed, the output voltage is recovered.
