7.3.8.4 Thermal Shutdown

To avoid thermal damage of the device, the temperature of the die is monitored. The device stops operation once the sensed temperature rises over the typical thermal threshold 160 ˚C. After the temperature drops below the typical thermal shutdown hysteresis 25 ˚C, the converter returns to normal operation.
