  • Page 2: Evaluation Board

    Renesas PowerNavigator™ evaluation software from a PC running Microsoft Windows. The ISL8280MEVAL1Z can operate in Pin-Strap mode without needing the ZLUSBEVAL3Z adapter or PMBus communication. By default, the ISL8280MEVAL1Z is set to a 1V output voltage with a 400kHz switching frequency, 49 AV gain, and 200kΩ RR. Key Features •...

  • Page 3: Specifications

    ISL8280MEVAL1Z 1. Overview Specifications The ISL8280MEVAL1Z is configured and optimized for the following operating conditions: • V = 4.5V to 15V • V = 1V • I = 10A OUT-MAX • f = 400kHz • AV gain multiplier = 2x, AV gain = 49, RR = 200kΩ...

  • Page 4: Functional Description

    ISL8280M datasheet for typical application recommended values. 11. To change the soft-start ramp rate, RR, and AV gain multiplier, disconnect the ISL8280MEVAL1Z from the setup and populate 1% standard 0402 resistors at the R and R placeholder locations on the bottom layer.
  • Page 5 For best thermal performance, use enough trace width, copper weight, and proper connectors. The ISL8280MEVAL1Z is capable of operating at 10A full load current at room temperature without the need for additional cooling systems. However, if the ISL8280MEVAL1Z needs to operate at elevated ambient temperatures, the available output current needs to be derated.
