DATASHEET ISL8018 8A Low Quiescent Current High Efficiency Synchronous Buck Regulator FN7889 Rev 0.00 September 30, 2015 The ISL8018 is a high efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 8A continuous output current from a 2.7V to 5.5V input supply.

The output voltage is adjustable from 0.6V to VIN.

With an adjustable current limit, reverse current protection, prebias start and over-temperature protection, the ISL8018 offers a highly robust power solut
