MAX17623/MAX17624 EV Kits Setup Diagram Required Equipment One 2.9V to 5.5V DC, 1A power supply Load resistors capable of sinking up to 1A at 1.5V and 3.3V Digital multimeter (DMM) Procedure A typical bench setup for MAX17623/MAX17624 EV Kits is shown in Figure 1. The EV kits are fully assembled and tested. Follow the steps below to verify and test individual converters operation. Caution: Do not turn on power supply until all connections are completed. 1. Disable the power supply and set the input power supply at a voltage between 2.9V and 5.5V for MAX17623, or between 3.6V to 5.5V for MAX17624. 2. Connect the positive terminal and negative terminal of the power supply to the VIN pad and its adjacent GND pad of the converter under evaluation, respectively. 3. Connect a maximum 1A resistive load across the VOUT pad and its nearest GND pad of the corresponding converter. 4. Verify that shunts are installed in default position on jumpers (JU101 and JU201) (see Table 1 for details). 5. Select the shunt position on jumpers (JU102, JU202) according to the required mode of operation (see Table 2 for details). 6. Connect the digital multimeter (in voltage measurement mode) across the VOUT and its respective GND pad. 7. Turn on the input power supply. 8. Verify that the digital multimeter displays 1.5V for MAX17623, and 3.3V for MAX17624 output terminal voltages, respectively with respect to GND. www.maximintegrated.com Maxim Integrated 2
