ISL85003A Highly Efficient 3A Synchronous Buck Regulator

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 compact 3mmx4mm DFN package. The ISL85003 is designed on Renesas’ proprietary fab process that is designed to deliver very low rDS(ON) FETs with an optimized cu.
