Pin functions
N°
Pin
Function
1COMP
Error amplifier output. A simple RC series between this pin and ground is
needed to compensate the loop of the boost regulator.
2
RILIM
Output generators current limit setting. The output current of the ROWs can
be programmed connecting a resistor to SGND.
3
BILIM
Boost converter current limit setting. The internal MOSFET current limit can
be programmed connecting a resistor to SGND.
4FSW
Switching frequency selection and external sync input. A resistor to SGND
is used to set the desired switching frequency. The pin can also be used as
external synchronization input. See Section 7.3 on page 25 for details.
5MODE
Current generators fault management selector. It allows to detect and
manage LEDs failures. See Section 9.2 on page 36 for details.
6
AVCC
+5 V analog supply. Connect to LDO5 through a simple RC filter.
7LDO5
Internal +5 V LDO output and power section supply. Bypass to SGND with a
1
µF ceramic capacitor.
8
VIN
Input voltage. Connect to the main supply rail.
