PIN FUNCTIONS
Pin # Name Description
1, 2
NC
3, 10
GND Ground.
No Connect.
4
C1A
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 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 All of the LEDs regulate at the same current. See
Setting the LED Current.
Enable Input. Drive EN high to turn on the MP1519L, drive EN low to shutdown the MP1519L.
To use burst-mode brightness control, drive EN with a PWM signal. See
Burst Mode Dimming.
LED1 the cathode at LEDC.
LED2 the cathode at LEDC.
LED3 the cathode at LEDC.
