TIDM-PSFB-DCDC: Recommend DCDC

Part Number: TIDM-PSFB-DCDC

Tool/software:

Dear TI experts,

Recently I am searching a  DCDC which has very low Rth_ja , because the output power dissipation is very high , could you help to recommend one suitable DCDC. 

The detail requirement as follows :

1. Input voltage range from 14V to 60V 

2. Output voltage is 12V

3. Output current is 2.2A

4. Maximum ambient temperature up to 95℃ 

5. Automotive grade 

To be honest I am worry about the heating and thermal issue , because I don't have enough space for cooling copper of DCDC , so pls. recommend some suitable DCDCs and mark the minimum cooling copper area? 

Thanks a lot!
