Unauthorized Photocopy and Duplication Prohibited. © 2016 MPS. All Rights Reserved. QUICK START GUIDE Signal connection: 1. Connect the positive and negative terminals of the power supply (3V ~ 30V) to the VIN and GND pins on the EV board, respectively. 2. Connect the positive and negative terminals of the load panel (8 strings) to the Vout and LED1~8 pins on the EV board, respectively. For unused string, it is recommended to connect the unused LEDX pin to GND by a 0Ω resister. 3. Connect EN pin to enable signal(High level>1.5V). 4. Please connect SCL, SDA and GND of EV board to SCL, SDA and GND of a programmable kit with I2C interface, respectively, as picture 3 shows. 5. If work in external dimming mode, please add PWM input signal to PWM terminal on the EV board. If work in internal dimming mode, nothing is need for PWM pin or pull PWM pin to GND. Picture 3 —I2C Connection Diagram Power on sequence: 1. Vin power on 2. EN power on 3. Setting Register by I2C interface as picture 4 shows: (Refer to the “GUI user guide” in another file.) 4. PWM signal on and the LED string should be ignited. Program the PWM duty cycle to dim the LED current. Picture 4 —MP3376 GUI Interface |
