ISL85003A Overview
DATASHEET ISL85003, ISL85003A Highly Efficient 3A Synchronous Buck Regulator The ISL85003 and ISL85003A are synchronous buck regulators with integrated high-side and low-side FETs. The regulator can operate from an input voltage range of 4.5V to 18V while delivering a very efficient continuous 3A current. This is all delivered in a very pact 3mmx4mm DFN package.
