ISL8215M Single-Channel DC-to-DC Step Down Power M

Intersil's ISL8215M power module is a single-channel synchronous step-down complete power supply capable of delivering up to 15 A of continuous current. Operating from a single 7 V to 42 V wide input power rail and integrating the controller, power inductor, and MOSFETs, the ISL8215M is optimized for space constrained and battery operated applications.

With high efficiency, including a selectable light load mode, and low thermal resistance, the ISL8215M permits full power operations without any heatsink over most conditions. It also provides fast transient response and excellent loop stability while a 40 ns typical minimum on-time allows single step low duty cycle down conversions to point-of-load voltages.

Offered in a compact RoHS compliant thermally enhanced 13 mm x 19 mm x 5.3 mm HDA package, the ISL8215M only requires a few external components to operate with its pin strapping configuration technology and provides high power density solution in a reduced footprint.
