MAX16818: FAQ

Was this helpful?

For MAX16818, what is the function of the 0.6V voltage between the Sense + and Sense- pins?

The current-sense resistor between Sense + and Sense- of the MAX16818 is used to detect the LED current and adjust to the required LED current.
How I could dynamically control the LED current with an analog voltage created by a DAC in a MAX16818 application?

It is possible to use a DAC to provide a voltage to the MAX16818 so that the current from the LED currents is regulated. One limiting factor is the common mode range of the current-sense amplifier CA inside…
