EV2364DF-00A
1.5A, 23V, 1.4MHz Dual
Step-Down Converter Evaluation Board
GENERAL DESCRIPTION
The EV2364DF-00A is an evaluation board for
the MP2364, a dual output, monolithic
step-down switch mode converter with built-in
internal power MOSFETs. It achieves 1.5A
continuous output current for each output over
a wide input supply range with excellent load
and line regulation.
Current mode operation provides fast transient
response and eases loop stabilization.
Fault condition protection includes cycle-by-cycle
current limiting and thermal shutdown. In
shutdown mode the regulator draws 40µA of
supply current.
The MP2364 requires a minimum number of
readily available standard external components.

QUICK START GUIDE
The output voltages of this board are set to 3.3V (VOUTA) and 2.5V (VOUTB). 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 both outputs, attach the positive and negative ends of the second load to
the VOUTB and GND pins, respectively.
2. Preset the power supply output to 4.75V to 23V 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 MP2364 will automatically startup.
5. To use the Enable function, apply a digital input to EN pin. Drive EN higher than 2.5V to turn on
the regulator and less than 0.7V to turn it off.
6. The Output Voltages VOUTA and VOUTB can be changed by varying R1 and R4, respectively.
Calculate the new values by the following formulae:
R1
=
R6
×
⎜⎜⎝⎛
VOUTA
0.92
− 1⎟⎟⎠⎞
R4
=
R3
×
⎜⎜⎝⎛
VOUTB
0.92
− 1⎟⎟⎠⎞
Where R6 = 10kΩ and R3 = 10kΩ
Example:
For VOUTA = 3.3V:
R1
=
10kΩ
×
(

=
25.9kΩ
Therefore, use a 25.5kΩ standard 1% value resistor.
