Name
Description
1
VOUT
Boost Output Voltage
. Output of the boost regulator. Connect the LEDs to this pin. Connect COUT
(Output Capacitor) to GND.
2
VIN
Input Voltage
. Connect to power source and decouple with CIN to GND.
3
EN
Enable Brightness Control
. Program dimming levels by driving pin with digital pulses.
4
FB
Voltage Feedback
. The boost regulator regulates this pin to 0.253V to control the LED string current.
Tie this pin to a current setting resistor (RSET) between GND and the cathode of the LED string.
5
SW
Switching node
. Tie inductor L1 from VIN to SW pin.
6
GND
Ground
. Tie directly to a GND plane.
