Thermal Considerations
To predict the approximate cooling needed for the SIP, deter-
mine the power dissipated as heat by the unit for the particu-
lar application. Figures 29—32 show typical heat dissipation
for the SIP over a range of output currents.
Figure 27. Thermal Test Setup.
Proper cooling can be verified by measuring the power SIP’s
temperature at lead 7 of Q31 as shown in Figure 28.
Figure 28. Temperature Measurement Location.
The temperature at this location should not exceed 115 °C.
The output power of the SIP should not exceed the rated
power for the SIP as listed in the Ordering Information table.
Convection Requirements for Cooling
To predict the approximate cooling needed for the SIP, deter-
mine the power dissipated as heat by the unit for the particu-
lar application. Figures 29—32 show typical heat dissipation
for the SIP over a range of output currents.
