Efficiency is a misleading number for comparison of switching regulators. The efficiency number can be manipulated by the input and output voltage, while power loss is more tightly tied to the actual circuit. This video explains why.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
