Intersil – ISL85410/15/18

Intersil’s ISL85410/15/18 switching regulators are designed to support a wide range of input and output voltages to address multiple voltage rail requirements within complex systems. The pin-compatible devices integrate both high-side and low-side FETs, eliminating the need for an inefficient low-side diode, resulting in reduced board space and BOM cost and improved efficiency in a variety of industrial and medical applications.

The ISL85410, ISL85415 and ISL85418 sync buck regulators are pin-to-pin compatible, providing system designers with a versatile down-converting solution that can be used to support a wide input voltage range from 3V to 36V with 500mA to 1A options. Designers can easily reuse a single proven, reliable layout for different power levels allowing for enhanced flexibility, reduced design time and decreased time to market.
