TPS62A03: θJA confirmation for TPS62A03DRLR

Part Number: TPS62A03

Tool/software:

Hi TI team,

Based on the datasheet, the θJA is 157.3. This data is very high for a power chip.

Can you confirm if there is any error in this data?

If the condition are:

Vin: 5V, Vout: 4.2V, Iout: 3A, efficiency:92.5%

Then the temp. rise will be 158.38.
