The ISL9104xIRUxEVAL1Z series of evaluation kits provide a test platform for the ISL9104 and ISL9104A 4.3MHz low quiescent current, high-efficiency integrated step-down regulators. The ISL9104 is capable of delivering 500mA output current. For the adjustable output option, the output voltage can be programmed through the external feedback resistors R1 and R2 on the board (on board the default output voltage is set to be 1.6V but it can be programmed for the range of 0.8V to VIN). It is also offered in many fixed output voltage options including 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, and 3.3V.

The complete ISL9104 regulator is located at the center of the board. On the left side of the board are the connectors for the input power source (VIN and GND). The output connectors are located on the right side (VO and GND). Jumper JP1 allows the user to enable or disable the IC.
