QUICK START GUIDE

The output voltage of this board is set to 1.8V.

1. Connect the positive and negative terminals of the load to the VOUT and GND pins respectively.

2. Preset the power supply output between 2.5V and 6.5V, and then turn off the power supply.

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

pins, respectively.

4. Turn the power supply on. The board will automatically start up.

5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 1.2V to turn

on the regulator or less than 0.4V to turn it off.

6. The default resistor values on the board are R1=26.1kΩ and R2=10kΩ. Changing these resistor

values will change the output voltage. Use the following equation to determine resistor values

for different output voltages:
