ISL8018

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. 100% duty-cycle operation allows less than 250mV dropout at 8A output current. Adjustable frequency and synchronization allow the ISL8018 to be used in applications requiring low noise. The ISL8018 can be configured for discontinuous or fo...
