QUICK START GUIDE

The output voltage of this board is set to 1.8V. The EN pin is connected to BIAS with a jumper for

automatic startup. You can connect EN to GND to disable the MP2005

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

2. Attach the input voltage (2V ≤ VIN ≤ 5V) and input ground to the VIN and GND pins,

respectively.

3. Attach the BIAS voltage (3.5V ≤ VBIAS ≤ 5.5V) and BIAS ground to the BIAS and GND pins,

respectively.

4. The VIN voltage and BIAS voltage can be set up to same voltage but it has to meet :

VIN=VBIAS>(1.8V + VOUT )and VBIAS>2.7V

5. The default resistor values on the board are R1=26.1kΩ and R2=10kΩ. Changing these resistor

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

for different output voltages:
