4.3. PTC Thermal Tab Calculation Options

The Thermal tab of the PTC offers three calculation modes.

The three modes are as follows:

  • You enter the ambient and maximum junction temperatures and the PTC calculates all the thermal parameters, including the maximum case temperature that ensures the set junction temperature is not exceeded. In this case a CFD analysis with the CTM is necessary to calculate the TCASE and compare it with the PTC results.
  • You enter the available cooling solution in form of the ΨCA and the PTC then provides all the thermal parameters, as well as the temperature and power margins.
  • You enter the cooling solution and maximum junction temperature. In this case the PTC provides all the thermal parameters and determines the ambient temperature that meets the specified design inputs.
