EV0035 – 6 WHITE LEDs, 20mA PRECISION WLED DRIVER EVALUATION BOARD
QUICK START GUIDE
1. Solder LED1 – LED6 onto the board.
2. Connect VCC to the power source’s positive output.
3. Connect GND to supply ground.
4. Remove the jumper J1 to allow the MP1523 to automatically start when power is applied. Place the
shorting clip across J1 to disable the MP1523. A logic signal may be applied to EN to
enable/disable the MP1523, provided the shorting clip is not installed across J1.
5. To dim the LEDs, remove the shorting clip from J1 and apply a PWM signal to the EN pin. Adjusting
the duty cycle of the PWM signal determines the brightness of the LEDs.
