EV0022 (MP1522) — PRECISION 6 WHITE LED DRIVER EVALUATION BOARD
QUICK START GUIDE
1. Connect LEDs to LED1 – LED6 terminals.
2. Preset Power Supply to 3V ≤ V_CC ≤ 5.5V.
3. Turn Power Supply off.
4. Connect Power Supply terminals to:
a. Positive (+): VCC
b. Negative (–): GND
5. Turn Power Supply on after making connections.
6. Remove the jumper J1 to allow the MP1522 to automatically start when power is applied. Place
the shorting clip across J1 to disable the MP1522. A logic signal may be applied to EN to
enable/disable the MP1522, provided the shorting clip is not installed across J1.
7. To dim the LEDs remove the shorting clip from J1 and apply a PWM signal to the EN pin. The
duty cycle of the PWM signal determines the LED current.
