LED1~6 pins on the EV board, respectively.

2. Connect the positive and negative terminals of the power supply (3V ~ 25V) to the VIN and

GND pins on the EV board, respectively.

3. Drive EN pin high (5V) to enable the MP3366

4. Drive PWM pin with 200Hz~20kHz pulse signal, the dim duty is low to 1% in Mix dim mode. A

680pF Ceramic Capacitor that connected between PWM pin and GND can eliminate the noise

from PWM input.
