6.3.6 Overvoltage Protection

The TPS5683x has the overvoltage protection feature. When the output voltage becomes higher than 125% of the target voltage, the OVP is triggered. The output discharges after a deglitch time of 32us and both the high-side MOSFET driver and the low-side MOSFET driver turn off. When the overvoltage condition is removed, the output voltage recovers.
