There are several inputs related to thermal management and use case power consumption. TI has assumed a thermal management strategy and use-case power. The user may alter these assumptions to meet their specific use case. The most critical parameter to result from these equations is the maximum junction temperature. Be sure not to exceed the maximum junction temperature rating of the component. The higher the junction temperature, the larger the raw (base) FIT rate will be.
