Intersil – ISL8018: 8A Low Quiescent Current High Efficiency Synchronous Buck Regulator

Power Regulation, Conversion and Management

The ISL8018 is a high efficiency, monolithic, synchronous step down DC/DC converter that can deliver up to 8A continuous output current from 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, pre-bias 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.
