Hello All,
There is a D-PAK on the top of the PCB. The heatsink plane is attached
to the bottom of the PCB. How much power could be possible to dissipate
at this D-PAK, i.e. what would be the ballpark of Rt ?
The PCB is double sided 2oz 1.5mm FR-4. The area of the solid copper
around the part is 1 sq.in. on the top and bottom. It is possible to put
as many plated vias as we want. The heatsink plane temperature can be
considered to be uniform; the Rt is 2C/W.
