7.3.4 Overvoltage Protection

The TPS56624x has the overvoltage protection feature. When the output voltage becomes higher than the OVP threshold, OVP is triggered with a 24-μs deglitch time. Both the high-side MOSFET driver and the low-side MOSFET driver are turned off. When the overvoltage condition is removed, the device returns to switching.
