ISL78235 Overview
ISL78235 5A Automotive Synchronous Buck Regulator The ISL78235 is a highly efficient, monolithic, synchronous step-down DC/DC converter that can deliver 5A of continuous output current from a 2.7V to 5.5V input supply. The device uses peak current mode control architecture to achieve very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL78235 integrates a...
