The thermal shutdown temperature is about 150C. This value can vary over a wide range and is not tested nor gauranteed.

Thermal Protection
Internal thermal shutdown circuitry protects the LM22671 should the maximum junction temperature be
exceeded. This protection is activated at about 150°C, with the result that the regulator will shutdown until the
temperature drops below about 135°C.
