QUICK START GUIDE

The output voltage of this board is set to 1.2V. The EN pin is connected to ground with a 10kΩ resistor

for automatic startup. You can connect EN to VIN to disable the MP2000.

1. Attach the positive and negative ends of the load to the VOUT and GND pins, respectively.

2. Attach the input voltage (1.35V ≤ VIN ≤ 6V) and input ground to the VIN and GND pins,

respectively.

3. The default resistor values on the board are R1=28.7kΩ and R2=20kΩ. Changing these resistor

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

for different output voltages:
