Whitepaper: How to Use Circuit Models in Thermal Calculations

November 24, 2016

circuit thermal modelThermal design is one of the most challenging elements of power system development. System requirements demand more power from less space, making it harder to ensure that the cooling removes sufficient heat to maintain the internal temperature of the component below the maximum allowed. Even when operating below the data sheet maximums, elevated temperatures reduce reliability: it’s always better to operate an electronic device at as low a temperature as possible.

Thermal circuit models simplify the calculations required when developing a power system, using resistors, current sources and voltage sources as analogies to thermal resistance, heat sources and temperature sources.

This white paper explains how to make use of circuit models and information from data sheets to make thermal calculations that will ensure reliable operation of your power system. Simply fill in the form below to download the white paper.
