Thermal Performance
(Continued)
For LLP-6 package, the integrated circuit die is attached to
leadframe die pad which is soldered directly to the printed
circuit board. This substantially decreases the junction to
ambient thermal resistance (
θ
JA
). By providing suitable
means of heat dispersion from the IC to the ambient through
exposed copper pad, which can readily dissipate heat to the
surroundings,
θ
as low as 40C / Watt is achievable with
the package. The resulting Trise for the driver example
above is thereby reduced to just 5.5 degrees.
Therefore T
RISE
is equal to
T
RISE
= 0.138 x 40 = 5.5C
