The datasheet values for these symbols are given so that one
might compare the thermal performance of one package
against another. To achieve a comparison between pack-
ages, all other variables must be held constant in the com-
parison (PCB size, copper weight, thermal vias, power
dissipation, V

LM3410 Thermal Models
Heat is dissipated from the LM3410 and other devices. The
external loss elements include the Schottky diode, inductor,
and loads. All loss elements will mutually increase the heat
on the PCB, and therefore increase each other’s tempera-
tures.
