Please review the latest information published by Renesas Electronics Corp. through various means, including the Renesas Electronics Corp. website ( Users Manual ISL8225MEVAL4Z Evaluation Board The ISL8225M is a complete, dual step-down switching mode DC/DC power 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 V setting resistors. OUT The simplicity of the ISL8225M is its off-the-shelf, unassisted implementation. Patented current sharing in multiphase operation greatly reduces ripple currents, BOM costs, and complexity. The ISL8225M has a thermally enhanced, compact 17mmx17mmx7.5mm QFN package that operates at full load and over-temperature without requiring forced-air cooling. Easy access to all pins, with few external components, reduces PCB design to a component layer and a simple ground layer. This ISL8225MEVAL4Z evaluation board is designed for dual 15A output applications. Optionally, this board can easily be converted for 30A single output use. Multiple ISL8225MEVAL4Z boards can be cascadable through the SYNC and CLKOUT pins to operate with phase shifting, for paralleling or multiple output use. The input voltage of this board is 4.5V to 20V and the default outputs on this board are set at 1.2V and 1.5V.
