Note 18:
This curve shows the LM4868MTE’s thermal dissipation ability at different ambient temperatures given these conditions:
500LFPM + JEDEC board:
The part is soldered to a 1S2P 20-lead exposed-DAP TSSOP test board with 500 linear feet per minute of forced-air flow across
it.
Board information
- copper dimensions: 74x74mm, copper coverage: 100% (buried layer) and 12% (top/bottom layers), 16 vias under the exposed-DAP.
