Attention: Destruction or malfunction, TQMLX2160A heat dissipation
The TQMLX2160A belongs to a performance category in which a cooling system is essential.
It is the user’s sole responsibility to define a suitable heat sink (weight and mounting position)
depending on the specific mode of operation (e.g., dependence on clock frequency, stack height,
airflow, and software).
Particularly the tolerance chain (PCB thickness, board warpage, BGA balls, BGA package, thermal pad,
heatsink) as well as the maximum pressure on the LX2160A must be taken into consideration when
connecting the heat sink.
The LX2160A is the highest component on the TQMLX2160A. Inadequate cooling connections
can lead to overheating of the TQMLX2160A and thus malfunction, deterioration or destruction.
