EV2106DQ/DK-00A – 2.6V TO 15V IN, 1.5A OUT SYNCHRONOUS BUCK EV BOARD
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 positive end and negative end of load to OUT and GND pins, respectively.
2. Attach input voltage (2.6V ≤ V_IN ≤ 13.5V) and input ground to IN and GND pins, respectively.
3. A pull-up resistor has connected the EN pin to the IN pin, so the MP2106 will startup
automatically without applying an external voltage to the EN pin.
4. The output voltage V_OUT can be changed by varying R3. Calculate the new value using the
formula:
R3 = R4 × ( ^VOUT − 1)
V_FB
where V_FB = 0.9V and R4 = 10kΩ.
For example, for V_OUT = 2.5V:
R3 = R4 × ( ^VOUT − 1) = 10kΩ × ( ^2.5V − 1) = 17.78kΩ ~ 17.8kΩ
V_FB
0.9V
for the closest standard 1% value.
See Maximum Duty Cycle limits to determine allowable output voltages.
