3A super-cap back-up chip is up to 94% efficient

Maxim has introduced 3A controller for supercapacitors used to back-up battery-powered low-voltage power rails. Called MAX38889, it is rated for operation between 2.5V and 5.5V on the supplied rail and 500mV to 5.5V on the capacitor. The converter bucks down from a powered voltage rail to the supercapacitor and, when the power source is removed, ...
