Power Supply

Power supplies are fundamental to electronic devices, from battery-powered portables to appliances that plug into wall outlets. No matter the device, increasing power supply efficiency is critical to reducing total power consumption. Additionally, protection against overcurrent events is important when it comes to system reliability and safety. Allegro current sensors combine very small footprints with high voltage isolation and fast response times that allow designers to reduce product sizes while improving reliability and protecting users.
