QUICK START GUIDE
The output voltage of this board is set to 5V. The board layout accommodates most commonly used
inductors and output capacitors.
1. Attach the positive and negative ends of the load to VOUT and GND, respectively.
2. Attach the input voltage (6.5V
V
IN
32V) and input ground to VIN and GND, respectively.
3. To enable to the MP1591, apply a voltage (V
EN
2V) to the EN pin. To disable it, connect the
EN pin to ground.
4. The REF pin outputs a 5V reference voltage. If used, a 0.01
μ
F capacitor should be connected
from this pin to GND to reduce switching ripple. Leave unconnected if not used.
5. The output voltage V
