QUICK START GUIDE
The output voltage of this board is set to 1.8V. The board layout accommodates most commonly used
inductors and output capacitors.
1. Attach the positive and negative ends of the load to the VOUT and GND pins, respectively.
2. Attach the input voltage (2.6V
≤
V
IN
≤
6V) and input ground to the IN and GND pins,
respectively.
3. A pull-up resistor has connected the RUN pin to the VIN pin, so the MP2108 will startup
automatically without applying an external voltage to the RUN pin.
4. The output voltage V

can be changed by varying R3. Calculate the new value using the
