equivalent θ JA for the noted conditions. These equivalent
θ JA parameters are correlated to the measured values, and
improve with air-?ow. The case temperature is maintained

Thermal Considerations and Output Current Derating
The power loss curves in Figures 8 and 13 can be used
in coordination with the load current derating curves in
Figures 9 to 12, and Figures 14 to 15 for calculating an
approximate θ JA for the module with various heatsink-
ing methods. Thermal models are derived from several

4W maximum power dissipation in the total module with
top and bottom heatsinking, and 2W power dissipation
through the top of the module with an approximate θ JC
between 6°C/W to 9°C/W. This equates to a total of 124°C
at the junction of the device.
Safety Considerations
The LTM4600 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 should be
provided to protect each unit from catastrophic failure.
