QUICK START GUIDE

The output voltage of this board is preset to 3.3V. The board is laid out to accommodate most

commonly used inductors and output capacitors.

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

2. Connect the input voltage (4.75V ≤ VIN ≤ 23V) and input ground to the VIN and GND pins,

respectively.

3. To turn on the MP2358, apply an enable voltage VEN to the EN pin. Drive EN higher than 1V to

turn on the MP2358 or lower than 0.4V to turn it off.

4. The output voltage VOUT can be programmed by varying R1. Calculate the new value using the

formula:
