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 solution. It uses current control architecture to deliver fast transient response and excellent loop stability. The ISL8018 integrates a pair of low ON-resistance P-channel and N-channel internal MOSFETs to maximize efficiency and minimize external component count.
