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 OUT and GND pins respectively.

2. Attach an input voltage 2.6V

respectively.

3. To enable the MP1567 apply a voltage, 2V

connect the EN pin to ground.
