QUICK START GUIDE

1. Connect the positive and negative terminals of the power supply (3V ~ 12V) to the VIN and GND

pins on the EV board, respectively.

2. LED string is connected to LED+ and LED- terminal respectively;

3. Drive EN pin high to enable the MP3306.

4. The DIM terminal is used for Analog/PWM dimming. When LPF capacitor is place at the PWO pin,

MP3306 works in analog dimming mode by filtering the input PMW pulse. When PWM pin is float,

MP3306 works in PWM dimming mode.

5. The LED current is set by the resistor at FB pin.

6. MP3306 has a N-channel MOS, which is used to accomplish short Vout to GND protection and

disconnecting Vout from Vin at shutdown mode. if don’t need this function, it can be disabled by

short the JP2.
