PIN FUNCTIONS
Pin # Name Description
LED4 #4 LED Driver. Connect the #4 LED between LED4 and LEDC, with the anode at LED4, and
the cathode at LEDC. If the #4 LED is not used, leave LED4 unconnected.
2
NC
No Connect.
3, 10
GND Ground.
Charge Pump Capacitor #1 Positive Node. Connect the positive side of the #1 charge pump
capacitor to C1A. Typical applications require C1 to be 1μF.
BATT Battery Power Input. Connect the 2.5V to 5.5V input source between BATT and GND. Bypass
BATT to GND with a 1μF or greater capacitor.
Charge Pump Capacitor #2 Positive Node. Connect the positive side of the #2 charge pump
capacitor to C2A. Typical applications require C2 to be 1μF.
Charge Pump Capacitor #1 Negative Node. Connect the negative side of the #1 charge pump
capacitor to C1B.
LED Common for the Cathodes. Connect the cathodes of the LEDs to LEDC and to a 4.7μF
bypass capacitor. Do not connect to any other ground, supply or pin.
Note: Exposed pad on backside is connected to this pin. Do Not Ground.
Charge Pump Capacitor #2 Negative Node. Connect the negative side of the #2 charge pump
capacitor to C2B.
RADJ LED Current Adjust Input. Connect a resistor between RADJ and GND to set the LED current.
All of the LEDs regulate at the same current. See
Setting the LED Current.
Enable Input. Drive EN high to turn on the MP1519, drive EN low to shutdown the MP1519. To
use burst-mode brightness control, drive EN with a PWM signal. See
Burst Mode Dimming.
LED1 #1 LED Driver. Connect the #1 LED between LED1 and LEDC, with the anode at LED1, and
the cathode at LEDC. If the #1 LED is not used, leave LED1 unconnected.
LED2 #2 LED Driver. Connect the #2 LED between LED2 and LEDC, with the anode at LED2, and
the cathode at LEDC. If the #2 LED is not used, leave LED2 unconnected.
LED3 #3 LED Driver. Connect the #3 LED between LED3 and LEDC, with the anode at LED3, and
the cathode at LEDC. If the #3 LED is not used, leave LED3 unconnected.
