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.
