Pin Functions

PIN I/O DESCRIPTION
NAME WCSP WSON
ENA A3 2 I Enable pin, Bank A. Driving this pin high turns on the current source to Bank A outputs. Driving this pin low turns off the current source to Bank A outputs. An applied PWM signal reduces the LED current (between 0 mA and the maximum current set by ISET) as a function of the duty cycle of the PWM signal. ENA and ENB can be tied together. ENA can be left OPEN or connected to GND if not used. See the Application and Implementation section for more details.
D1A B3 3 O Diode source current output, Bank A. Connect to LED anode.
D2A C3 4 O Diode source current output, Bank A. Connect to LED anode.
ENB A2 1 I Enable pin, Bank B. Driving this pin high turns on the current source to Bank B outputs. Driving this pin low turns off the current source to Bank B outputs. An applied PWM signal reduces the LED current (between 0 mA and the maximum current set by ISET) as a function of the duty cycle of the PWM signal. ENA and ENB can be tied together. ENB can be left OPEN or connected to GND if not used. See the Application and Implementation section for more details.
VIN B2 9 I Supply input
GND C2 5, Pad — Ground
ISET A1 10 I An optional resistor can be connected between this pin and GND to set the maximum current through the LEDs. If no resistor is connected, ISET defaults to the internally programmed value.
D1B B1 8 O Diode source current output, Bank B. Connect to LED anode.
D2B C1 7 O Diode source current output, Bank B. Connect to LED anode.
NC — 6 — Not internally connected
