Overview
Description
The ISL85410DEMO1Z board is intended for use in point-of-load applications sourcing from 3V to 40V. The boards are used to demonstrate the performance of the ISL85410 wide VIN, low quiescent current, high-efficiency synchronous buck regulator with 1A output current.
The ISL85410 1A synchronous buck regulator provides an easy-to-use, high efficiency low BOM count solution for a variety of applications. The ISL85410 integrates both high-side and low-side NMOS FETs and features a PFM mode for improved efficiency at light loads.
Features
