TPS54610DRC thermal resistance from Junction to Board...

Dennis Kruger

Hi,

I am doing PCB thermal analysis with a TPS54610DRC. I need the thermal resistance from Junction to Board. The data sheet provides Junction to Ambient (18.2C/W) but our boards are cooled via a 'cold wall' not ambient air. I could not find SLMA002 application note.

Thanks in advance,

Dennis

The thermal information you are looking for is not available in all our datasheets. You can contact your local TI sales representative to help you request this information. Here is the link to get that information http://www-k.ext.ti.com/sc/technical-support/product-information-centers.htm?DCMP=TIHomeTracking&HQS=Other+OT+home_d_contact

For TI employees, this information is available if you search the internal for "thermal" or "theta JC" to find the link to the packaging group. The link to the packaging tea is also listed here for your reference https://sps04.itg.ti.com/sites/WW-HPA/hpa_pkg/Lists/Thermal%20Model%20Request%20Form3/NewForm.aspx
