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
