Hi may I know the ambient operating temperature for TEC controller IC?Especially for ADN8833. As data sheet only state for junction temp of the IC chipset but I would like to know more details on the operating temp for the IC.
The allowed ambient temperature depends on the power dissipation on the part, which can be estimated by Maximum_Output_Power *(1-Efficiency). The apps note below describes how to calculate ambient temperature using power loss and thermal resistance.
In general, the part can operate under 85C ambient. Careful estimation is needed if intend to go above that.
noted and thanks a lot for the help.
