Intersil's ISL8215M 15 A 42 V single-channel high efficiency dc-dc step-down power module

Intersil's ISL8215M power module is a single channel synchronous step-down complete power supply capable of delivering up to 15 a continuous current. Operating from a single 7 V to 42 V wide input power track, the ISL8215M incorporates controllers, power inductors and MOSFEts optimized for space-constrained and battery-powered applications.

With high efficiency, including optional light load mode and low thermal resistance, the ISL8215M allows full power operation without any radiator under most conditions. It also provides fast transient response and excellent loop stability, while the 40 ns typical minimum operating time allows single-step low duty ratio downconversion to point-of-load voltage.

The ISL8215M comes in a RoHs-compliant 13 mm x 19 mm x 5.3 mm HDA package with pin-strap-on configuration technology that requires only a small number of external components to operate and provides a high power density solution with a lower footprint.
