N°

Pin

Function

Slope compensation setting. A resistor between the output of the boost

9

SLOPE converter and this pin is needed to avoid sub-harmonic instability.

Refer to section 1.4 for details.

10

SGND

Signal ground. Supply return for the analog circuitry and the current

generators.

11

ROW1

Row driver output #1.

12

ROW2

Row driver output #2.

13

ROW3

Row driver output #3.

14

ROW4

Row driver output #4.

15

ROW5

Row driver output #5.

16

ROW6

Row driver output #6.

17

PGND

Power ground. Source of the internal power-MOSFET.

18

OVSEL

Over-voltage selection. Used to set the desired OV threshold by an external

divider. See section 1.2 for details.

19

LX

Switching node. Drain of the internal power-MOSFET.

20

DIM

Dimming input. Used to externally set the brightness of the LEDs by using a

PWM signal.

21

EN

Enable input. When low, the device is turned off. If tied high or left floating,

the device is turned on and a Soft-Start sequence takes place.

22

FAULT

Fault signal output. Open drain output. The pin goes low when a fault

condition is detected (see section 3.1 for details).

23

SYNC

Synchronization output. Used as external synchronization output.

24

SS

Soft start. Connect a capacitor to SGND to set the desired Soft-Start

duration.
