SN75976A-EP: How do we calculate Junction-to-board thermal resistance and the power consumption of this device.

Part Number: SN75976A-EP

How do we calculate Junction-to-board thermal resistance and the power consumption of this device. For thermal analysis we need this information.

THANKS IN ADVANCE

For power consumption, you can use the Cpd parameter.

Note, this is no load current. There will be additional power dissipation based on output loading.

With respect to junction to board thermal metric. I will request this get modeled. This process takes ~2weeks.

Wade

I have the thermal data for the SN75976A1MDGGREP

Theta JA-High K 41.9
Theta JC, top   9.1
Theta JB   7.4
Psi JT         0.3
Psi JB           7.4

Thanks for your patience.
