Power Consumption of Chip Solution

STEP 0: Pre-Calculation Summary

Formula Used

Power Consumption of Chip = Temperature Difference Transistors/Thermal Resistance between junction and Ambient
P_chip = ΔT/Θ_j
This formula uses 3 Variables

Variables Used

Power Consumption of Chip - (Measured in Watt) - Power Consumption of Chip is power consumed by the integrated chip when the current flows through it.
Temperature Difference Transistors - (Measured in Kelvin) - Temperature Difference Transistors is denoted by ΔT symbol.
Thermal Resistance between junction and Ambient - (Measured in Kelvin per Watt) - Thermal Resistance between junction and Ambient is defined as the rise in the resistance due to the heating effect in junction.

STEP 1: Convert Input(s) to Base Unit

Temperature Difference Transistors: 2.4 Kelvin --> 2.4 Kelvin No Conversion Required
Thermal Resistance between junction and Ambient: 3.01 Kelvin per Milliwatt --> 3010 Kelvin per Watt (Check conversion here)

How is heat flow determined?

The heat generated by a chip flows from the transistor junctions where it is generated through the substrate and package. It can be spread across a heat sink, and then carried away through the air by means of convection. Just as current flow is determined by the voltage difference and electrical resistance, the heat flow is determined by temperature difference and thermal resistance.
