PIN FUNCTIONS
V
OUT2
(Pin 7):
Drain of Output Disconnect PMOS.
Place a bypass capacitor from this pin to GND. See the
Applications Information section.
CAP2 (Pin 8):
Output of the OLED Driver. This pin is
connected to the cathode of the internal Schottky diode.
Place a bypass capacitor from this pin to GND.
SW2 (Pin 9):
Switch Pin. This is the collector of the in-
ternal NPN power switch. Minimize the metal trace area
connected to this pin to minimize EMI.
V
IN
(Pin 10):
Input Supply Pin. Must be locally by-
passed.
SW1 (Pin 11):
Switch Pin. Connect the inductor of the
white LED driver at this pin. Minimize metal trace area at
this pin to minimize EMI.
CAP1 (Pin 12):
Output of the White LED Driver. This pin is
connected to the cathode of the internal Schottky. Connect
the output capacitor to this pin and the sense resistor from
this pin to the LED1 pin.
Exposed Pad (Pin 13):
Ground. The Exposed Pad must
be soldered to the PCB.
