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 ISL8225MEVAL3Z evaluation board enables a single output by paralleling two phases to deliver 30A of continuous load current. The ISL8225M step-down power module supports input voltage from 4.5V to 20V and the output voltage ranges from 0.6V to 7.5V. With the single resistor modification, the output voltage can be easily adjusted to different voltages.

The ISL8225MEVAL4Z is designed to be a standard evaluation board such that it provides BNC, jumper and probe connections to make a more thorough evaluation of the power module. The ISL8225M is a true two-channel voltage regulator such that it has independent input supplies. This board allows such connection by separating the input connections. The outputs are also independent and the evaluation board is preset with 1.5V output on channel 1 and 1.2V output on channel two, each channel is capable of 15A of output current.
