The temperature will dependent on the use cause.

Higher Vout has higher power dissipation. Higher switching frequency can have higher power dissipation. High Duty cycle can have higher power dissipation.

The TPS548A28 datasheet has the SOA curves that show the ambient temperature where the device EVM works https://www.ti.com/lit/ds/symlink/tps548a28.pdf#page=9.
