Current Sensor to Make Power Supplies Smaller and Cheaper

Aceinna. Power supply circuits are literally everywhere. From the ubiquitous power bricks that recharge our phones to kilowatt server supplies in data centers, every modern electrified gadget has a switched-mode power supply circuit. Who wants to carry around a heavy laptop brick? What data center does not want to drive energy cost down while at the same time increasing compute capacity? These are just a few of the challenges facing today’s power supply designer. Aceinna’s new family of Anisotropic Magnetoresistive (AMR) isolated current sensors offer design engineers a new operating point for accuracy and bandwidth in a small low-cost surface-mount package.
