QUICK START GUIDE

The output voltage of this board is set externally which can be regulated as 1V, 1.2V, 1.5V or 1.8V by

choosing the jumper position. The input voltage can range from 8V to 18V. The minimum 8V input

voltage is limited by the EN signal, which is derived from VIN through a resistor divider. Lower input

voltage (as low as 4.5V) can be set by fine tuning the resistor divider values. The following is the

procedures to turn on the power module.

1. Put the jumper to the position to the desired output voltage setting.

2. Connect the positive and negative terminals of the load to the VOUT and GND pins,

respectively.

3. Preset the power supply output between 8V and 18V, and then turn off the power supply. Make

sure the power supply has high enough current limit to supply the current.

4. Connect the positive and negative terminals of the power supply output to the VIN and GND

pins, respectively.

5. Turn the power supply on. The power module will automatically start up.
