The ISL8012 is a high efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 2A continuous output current from a 2.7V to 5.5V input supply. It uses a current control architecture to deliver very low duty cycle operation at high frequency with fast transient response and excellent loop stability.
