Pack more power than ever in your small sensor
The current trend of creating smart factories using automation and data exchange in manufacturing technologies (also dubbed Industry 4.0) goes hand-in-hand with the advances in sensor technologies. As Internet of Things (IoT) devices and sensors become smaller and more complex, so do their on-board voltage regulators. They must deliver more power in a smaller space, with minimum heat generation, and must have ease of design for fast cycle time. How is this achieved?
