EV3213DH-00A – 700KHZ/1.3MHZ BOOST CONVERTER WITH A 3.5A SWITCH
EVALUATION BOARD
QUICK START GUIDE
The output voltage of this board is set to 12V. The board layout accommodates most commonly used
inductors and output capacitors.
1. Preset Power Supply to 2.5V ≤ V_IN ≤ 10V.
2. Turn Power Supply off.
3. Place jumper J1 at the H position for 1.3MHz operation, or at the L position for 700KHz
operation (the inductor may need to be adjusted accordingly).
4. Connect the power supply terminals to:
Positive (+): VIN
Negative (–): GND
5. Connect the load to:
Positive (+): VOUT
Negative (–): GND
6. Turn on the power supply after making connections.
7. The MP3213 is enabled automatically on the evaluation board once V_IN is applied. To disable
the MP3213, pull EN low.
8. The output voltage V_OUT can be changed by varying R1. Calculate the new value using the
formula:
R1
=
⎜⎜⎝⎛
V_OUT
V_FB
− 1_{⎟⎟⎠⎞}R2
Where V_FB = 1.25V and R2 = 10kΩ
For example, for V_OUT = 15V
R1 = ⎜⎛ ^15V − 1⎟⎞ × 10kΩ = 110kΩ
⎝ ^1.25V ⎠
Therefore use a 110kΩ standard 1% value.
