UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The junction temperature (TJ) of the device is monitored by an internal temperature sensor. If TJ exceeds the thermal shutdown temperature TSD of 160°C (typ), the device enters thermal shutdown. Both the high side and low side power FETs are turned off. When TJ decreases below the hysteresis amount of typically 20°C, the converter resumes operation, beginning with a soft start to the originally set VOUT (there is no R2D conversion of RVSEL). The thermal shutdown is not active in Power Save Mode.
