Intersil, a subsidiary of Renesas Electronics, has announced the first 42V single-channel DC/DC step-down power module. The ISL8215M delivers up to 15A of continuous current and operates from a single wide input voltage range including industry standard 12V, 18V, and 24V intermediate bus power rails.
The module offers adjustable output voltages from 0.6V to 12V and provides the highest power density of 60mA/mm2 in a 13mm x 19mm package. It’s 96.5% peak efficiency enables point-of-load (POL) conversions for FPGAs, DSPs, and MCUs in industrial, medical, RF communications, after-market automotive, and portable equipment carrying Li-ion batteries.

The ISL8215M is a complete DC-to-DC power supply comprising a controller, MOSFETs, inductor, and passive components inside a single encapsulated package to simplify system design and speed time to market. The module’s proprietary High-Density Array (HDA) package offers unmatched electrical and thermal performance through a single-layer conductive package substrate.
This reduces lead inductance and dissipates heat primarily through the system board. The device’s components are mounted to a copper lead-frame structure which allows the module to operate at full load over a wide temperature range with no airflow or heat sinks, further reducing size and cost.
Adjustable output voltage from 0.6V to 12V with +/- 1.5 % accuracy over line, load and temperature, and 40ns on-time low duty cycle.
Fault protections include input under-voltage lockout, over-temperature, programmable over-current, output over-voltage and output pre-bias startup ensure safe operation.
Complete 15A single-channel power supply integrates controller, MOSFETs, inductor, and passive components.
Dedicated enable pin and power-good flag simplify sequencing of system power rails with voltage tracking.
Operates from a single 7V to 42V wide input voltage range.
Up to 96.5% peak efficiency.
Adjustable switching frequency from 300kHz to 2MHz, with 300kHz default.
External clock signal synchronization up to 1MHz.
Selectable light-load PSM/DEM efficiency mode to extend battery life
Programmable soft-start reduces inrush current from the input supply
