Increasing Power in Small Smart-Home Hub


#1

Smart hubs are fast becoming a common household item. Used to wirelessly control door locks, lights, thermostats, audio and electric appliances, they are also equipped to send notifications to the homeowner (Figure 1). These wall-powered, soap-sized gadgets are packed with electronics and often include backup batteries in case of power outage. To fit in such a small space while minimizing heat generation, the on-board power management system must be small and efficient. This article reviews a typical approach for powering a smart hub. It then presents a new solution that delivers more efficient power in a smaller space, enabling longer backup battery run-times and smaller form factors to accommodate today’s smarter homes.
