QUICK START GUIDE
The output voltage of this board is set to 5V, –10V and 15V on VOUT, VN and VP, respectively. The
board layout accommodates most commonly used inductors and output capacitors.
1. Preset the power supply to 3V
≤
V
IN
≤
3.6V.
2. Turn off the power supply.
3. Connect the power supply terminals to:
a. Positive (+): VIN, EN
b. Negative (–): GND
4. Connect the load to:
a. Positive (+): VOUT, VP, GND (for the negative output)
b. Negative (–): GND, VN (for the negative output)
5. Turn on the power supply after making the connections.
6. The MP1541 is disabled on the evaluation board if only VIN is applied. To enable the MP1541,
EN needs to be pulled HIGH.
7. The output voltage V
OUT
can be changed by varying R1. Calculate the new value using the
formula:
