Pin Functions

PIN I/O DESCRIPTION
NUMBER NAME
A1 ISET I Full-scale LED current set pin. Connecting a resistor to the pin programs the full-scale LED current.
A2 IFB2 I Regulated current sink input pin
A3 IFB1 I Regulated current sink input pin
B1 PWM I PWM dimming signal input
B2 COMP O Output of the transconductance error amplifier. Connect external capacitor to this pin to compensate the boost loop.
B3 GND — Ground
C1 EN I Enable control and one-wire digital signal input
C2 VIN I Supply input pin
C3 SW I Drain connection of the internal power MOSFET
