4.1 Estimation with Junction-to-Ambient Thermal Resistance
An estimation of the chip junction temperature, T
where:
The junction-to-ambient thermal resistance is an industry standard value that provides a quick and easy estimation
of thermal performance. However, the answer is only an estimate; test cases have demonstrated that errors of a factor
