1A, 800mA, 500mA Synchronous Buck Regulator Demonstration Boards


The ISL85410DEMO1Z, ISL85418DEMO1Z, ISL85415DEMO1Z, and ISL85415DEMO2Z boards are intended for use for point-of-load applications sourcing from 3V to 36V (ISL85415) and 3V to 40V (ISL85410, ISL85418). The boards are used to demonstrate the performance of the ISL85410, ISL85418, ISL85415 wide VIN low quiescent current high efficiency synchronous buck regulators with 1A, 800mA, and 500mA output current.

ISL8541xEVAL1Z and ISL8541xEVAL2Z evaluation boards are also available!
