QUICK START GUIDE

The output voltages of this board are set to 3.3V (VOUTA), 1.8V (VOUTB), 12.8V (VOUTC) and 5V

(VOUTD). The board layout accommodates most commonly used inductors and output capacitors.

1. Attach the positive and negative ends of the first load to the VOUTA and GND pins,

respectively. If using other outputs, attach the positive and negative ends of their loads to the

respective VOUT and GND pins for the desired outputs.

2. Preset the power supply output to 5V to 23V and turn it off.

3. Connect the positive terminal of the power supply output to the VIN pin and the negative

terminal of the to the GND pin.

4. Turn on the power supply. The EV2364DF/1541DJ will automatically startup.

5. To use the Enable function, apply a digital input to the ENA/ENB pins. Drive EN higher than

2.5V to turn on the regulator and less than 0.7V to turn it off.
