Overview
Description
The ISL8225MEVAL2Z is a three module six-channel multiphased 90A output demo. This board highlights the simplicity of implementing both the multiphasing and current sharing of parallel modules. This solution requires minimal circuitry and layout complexity but provides phase shifting and accurate current balancing between the modules.
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 to have a complete, dual 15A design ready for use are the ISL8225M, a few passive components, and VOUT setting resistors.
