Type Description
1 BOOT Analog circuitry power supply connection
2DIM
Dimming control input. Logic low prevents the switching activity, logic
high enables it. A square wave on this pin implements LEDs current
PWM dimming. Connect to VIN if not used (see
Chapter 5.8
)
3 INH Inhibit pin. Connect to GND if not used.
4 COMP Analog circuitry
5FB
Feedback input. Connect a proper sensing resistor to set the LED
current
6 GND Ground connection
7 VIN Power input voltage
8 SW Switching node
-e.p.
Exposed pad to be connected to GND to increase the package
thermal performance and the device noise immunity
