Product Details
The DS2731 evaluation kit (EV kit) demonstrates all the features of the DS2731 battery-backup power-management IC. The EV kit includes an assembled and tested PCB for easy connection to power sources and a load. Three power sources—a 3.3V auxiliary supply, a 12V supply, and a single lithium-ion (Li+) battery—connect to the DS2731 EV kit to supply the high-efficiency, synchronous buck regulator and battery charger. The IC automatically selects the best-qualified power source for the buck regulator. Thresholds for low-battery voltage, charge regulation voltage and current, charge safety timer, and buck-output voltage are set by resistors.
