Powering Low-Power Sensors for the Internet of Things - April/May 2021
Low-power sensors for the Internet of Things will be embedded into streets, offices and factories to collect data for years and share it with the cloud, most likely wirelessly. The use of batteries as a power source is one of the key areas developers have to address. It comprises many issues around limited lifetimes, product sustainability, manufacturing materials, shipment issues and the disposal of the battery at the end of its life.

Novel GaN Design Reduces Volume of AC/DC Converters Substantially - April/May 2021
Power Integrations recently released a GaN-based IC called MinE-CAP, intended for use in a new generation of mobile credit card-sized chargers or offline power supplies. By halving the size of the high-voltage bulk electrolytic capacitors required in offline power supplies, this IC enables a reduction in adapter size of up to 40%. The device also reduces in-rush current making NTC thermistors unnecessary, increasing system efficiency and reducing heat dissipation.
