Data Sheet

Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

THERMAL RESISTANCE

Thermal resistance values specified in Table 3 are simulated

based on JEDEC specifications, unless specified otherwise, and

must be used in compliance with JESD51-12.

1 For θJC, 100 µm thermal interface material is used. Thermal interface material

is assumed to have 3.6 W/mK.

2 Using enhanced heat removal (printed circuit board (PCB), heat sink, and

airflow) techniques improves thermal resistance values.
