ISL8225MEVAL3Z: 0.6 ~ 6V @ 30A, 4.5 ~ 20V in

Summary

The ISL8225M is a complete, dual step-down switching mode DC/DC module. The dual outputs can easily be paralleled for single-output, high-current use. It is easy to apply this high-power, current-sharing DC/DC power module to power-hungry datacom, telecom, and FPGA applications. All that is needed in order to have a complete, 30A design ready for use are the ISL8225M, a few passive components, and VOUT setting resistors.

The ease of use virtually eliminates design and manufacturing risks while dramatically improving time to market. The simplicity of the ISL8225M is its off-the-shelf, unassisted implementation. Patented module structure allows for higher power density and better efficiency than competing solutions. Patented current sharing in multi-phase operation greatly reduces ripple currents, BOM costs, and complexity.

The ISL8225MEVAL3Z evaluation board enables a single output by paralleling two phases to deliver 30A continuous load current. The ISL8225M supports input voltage from 4.5 V to 20 V and the output voltage ranges from 0.6 V to 6 V. With the single resistor modification, the output voltage can be easily adjusted to different voltages.
