LED Driver
The 5.0V, 4.5V, or the 4.1V mode can be used depending on the forward voltage and load requirements of the
LED application. The LM2757 can be enabled/disabled by applying the appropriate combination of logic signals
on the M1 and M0 pins. LED current for each string in this application is limited by the voltage across the string's
ballast resistor, which is dependent on the output voltage mode selected and the V-I profile of each LED used.
