Intersil analog power module delivers 15 A at 42 V

September 10, 2017 ECD Staff

Intersil today announced a 42-V single-channel DC-to-DC step-down power module that delivers up to 15 A of continuous current. The ISL8215M operates from a single wide input voltage range that includes industry standards 12-, 18-, and 24-V intermediate bus power rails. The module offers adjustable output voltages from 0.6 to 12 V, and provides a power density of 60 mA/mm2 in a 13- by 19 mm package. Its 96.5% peak efficiency drives point-of-load (POL) conversions for FPGAs, DSPs, and MCUs in industrial, medical, RF communications, after-market automotive, and portable equipment that use Li-ion batteries.

The ISL8215M is a complete DC-to-DC power supply that includes a controller, MOSFETs, inductor, and passive components inside an encapsulated package to simplify system design and speed time to market. The module’s proprietary High Density Array (HDA) package offers excellent electrical and thermal performance through a single-layer conductive package substrate that reduces lead inductance and dissipates heat primarily through the system board. The ISL8215M’s components are mounted to a copper lead-frame structure that allows the module to operate at full load over a wide temperature range with no airflow or heatsinks, further reducing size and cost.

The ISL8215M also provides fast transient response and excellent loop stability while its 40-ns typical minimum on time allows single-step low duty cycle down conversions to point-of-load voltages. The device offers selectable light load efficiency to extend battery life in Li-ion powered applications, and support Energy Star compliant products. The device provides voltage, temperature and current protection features that ensure safe operation under abnormal operating conditions. The ISL8215M also provides automatic restart upon fault clearance to protect the load and system.

The ISL8215M power module is available now for $13.90 in lots of 1000. An ISL8215MEVAL1Z evaluation board can be purchased for $69.
