EV2360DG-00B – 1.8A, 24V, 1.4MHz STEP-DOWN CONVERTER in 2x2 QFN8 EV BOARD
QUICK START GUIDE
1. Connect the positive terminal of the load to VOUT pin, and the negative terminal of the load to
GND pin.
2. Preset the power supply output to 4.5V – 24V and turn off the power supply.
3. Connect the positive terminal of the power supply output to the VIN pin and the negative
terminal of the power supply output to the GND pin.
4. Turn the power supply on. The board will automatically startup.
5. To use the Enable function, apply a digital input to EN pin. Drive EN higher than 1.2V to turn on
the regulator, drive EN less than 0.4V to turn it off.
6. The output voltage V_OUT can be changed by varying R1. Calculate the new values by the
following formula:
R1
=
R2
×
⎜⎜⎝⎛
V_OUT
0.81
− 1_{⎟⎟⎠⎞}
Where R2 = 16.2kΩ
Example:
For V_OUT = 3.3V:
R1 = 16.2kΩ × ⎜⎛ ^3.3 − 1⎟⎞ = 49.8kΩ
⎝ ^0.81 ⎠
Therefore, use a 49.9kΩ standard 1% value resistor.
