2 Challenges for Switching Regulators in ET environments

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.
