Assumptions:
Vin = 3.6V worst case
VOUT = 1.47V worst case
IOUT = 5A continuous
TA = 40°C
Θ Case-to-Ambient = 5°C/W (assuming both a heatsink and a
thermally conductive material)
The power dissipation in this application is:
PD = (VIN - VOUT) * (IOUT) = (3.6-1.47) * (5) = 10.65W
From the specication table,
TJ = TA + (PD) * (
Θ Case-to-Ambient + ΘJC)
= 40 + (10.65) * (5 + 3) = 125°C
The junction temperature is within the maximum rating.
Junction-to-case thermal resistance is specied from the IC
junction to the bottom of the case directly below the die. This
is the lowest resistance path for heat ow. Proper mounting
ensures the best thermal ow from this area of the package to
the heat sink. Use of a thermally conductive material at the
case-to-heat sink interface is recommended. Use a thermally
conductive spacer if the case of the device must be electri-
cally isolated and include its contribution to the total thermal
resistance.
