PRODUCTION DATA
The high-current and high-voltage characteristics of the TPS7H1210-SEP means that, often enough, high power (heat) is dissipated from the device itself. This heat, if dissipated into the PCB, creates a temperature gradient in the surrounding area that causes nearby components to react to this temperature change (drift). In high-performance systems, such drift may degrade overall system accuracy and precision.
The heat generated by the device is a result of the power dissipation, which depends on input voltage and load conditions. Power dissipation (PD) can be approximated by calculating the product of the output current times the voltage drop across the output pass element, as shown in Equation 5:
Be sure the PCB is able to effectively dissipate the heat resulting from the power dissipation.
