Setting the LED Voltage Range
The MSL9082 LED driver board uses four different voltage ranges to power the LEDs, which are set through the S3
switch. The ranges are shown in Table 7. The MSL3162 automatically adjusts the LED voltage over a 7.4V range to
minimize power loss while maintaining enough current sink headroom to keep the LED string current accurate. Choose
an LED voltage range that suits the LEDs used so that the MSL3162 can adjust the voltage to optimize for the LED
voltage. For more information, consult the MSL3162 data sheet.
