Typical Performance Characteristics
MTE Specific Characteristics
Note 17: This curve shows the LM4863MTE’s thermal dissipation ability at different ambient temperatures given these conditions:
Non-MTE Specific Characteristics
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.
500LFPM + 2.5in
2.5in
Not Attached: The part is not soldered down and is not forced-air cooled.
2
