APPLICATIONS INFORMATION
Thermal Considerations and Output Current Derating
The power loss curves in Figures 7 and 8 can be used
in coordination with the load current derating curves in
Figures 9 to 14 for calculating an approximate θ JA for the
module with various heat sinking methods. Thermal models
are derived from several temperature measurements at
the bench and thermal modeling analysis. Thermal Ap-
plication Note 103 provides a detailed explanation of the
analysis for the thermal models and the derating curves.
Tables 3 and 4 provide a summary of the equivalent θ JA
for the noted conditions. These equivalent θ JA parameters
are correlated to the measured values, and are improved
with air flow. The case temperature is maintained at 100°C

or below for the derating curves. The maximum case
temperature of 100°C is to allow for a rise of about 13°C
to 25°C inside the μModule with a thermal resistance θ JC
from junction to case between 6°C/W to 9°C/W. This will
maintain the maximum junction temperature inside the
μModule regulator below 125°C.
Safety Considerations
The LTM4601 modules do not provide isolation from
V IN to V OUT . There is no internal fuse. If required, a
slow blow fuse with a rating twice the maximum input
current needs to be provided to protect each unit from
catastrophic failure.
