Most common applications requiring ET capabilities include:

• Aerospace and Defense
• Industrial
• Medical
• Military

Texas Instruments devices capable to operate in extended temperatures strive in space constrained applications and wide thermal requirements. Having -55°C on the low operating temperature allows capability for more applications, for example, powering components that might be placed externally to an aircraft and across many military applications.

When working with switching regulators, power is dissipated in the form of heat. This heat has to be managed properly so that the converter maintains operation within the recommended temperature limits. Otherwise, the lifetime and performance of the device will not meet expectations. Thermal management is one of the most important aspects of designing power supplies. The goal of thermal management is to keep the maximum junction temperature of the device at or below a safe value.
