FUNCTION
Enable Input Pin. The EN pin is an active high Control. Pull EN pin above 1.3V to enable the device; pull EN
pin below 0.3V to disable the device.
LED On/Off Control Pin. Allow disabling or enabling a combination of LEDs.
LED On/Off Control Pin. Allow disabling or enabling a combination of LEDs.
LED On/Off Control Pin. Allow disabling or enabling a combination of LEDs.
LED Current Set Input. Connect a resistor from ISET to GND to set the LED current. VISET is typically 1.2V.
Output Voltage Pin. Connect VOUT to the LED anode. Connect a 1µF capacitor from VOUT to GND.
Supply Voltage Input Pin. Connect a 1µF capacitor from VIN to GND.
Bucket Capacitor1 Positive Terminal. Connect a 1µF capacitor from C2+ to C2-.
Bucket Capacitor1 Negative Terminal. Connect a 1µF capacitor from C2+ to C2-.
Bucket Capacitor1 Positive Terminal. Connect a 1µF capacitor from C1+ to C1-.
Bucket Capacitor1 Negative Terminal. Connect a 1µF capacitor from C1+ to C1-.
Device Ground Pin.
LEDs Cathode Connection. The LED current flows from VOUT through LED into ILED_ pin. The charge
pump regulates the lowest VILED to 180mV. Connect ILED_ pin to VOUT if the LED is not used.
