Pin functions
Pin connection (through top view)
Error amplifier output. A simple RC series between this pin and ground is
needed to compensate the loop of the boost regulator.
Output generators current limit setting. The output current of the ROWs can
be programmed connecting a resistor to SGND.
Boost converter current limit setting. The internal MOSFET current limit can
be programmed connecting a resistor to SGND.
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
Current generators fault management selector. It allows to detect and
manage LEDs failures. See
+5 V analog supply. Connect to LDO5 through a simple RC filter.
Internal +5 V LDO output and power section supply. Bypass to SGND with a
1 µF ceramic capacitor.
Input voltage. Connect to the main supply rail.
