The Atmel® MSL2021, a two-channel LED driver, is the first LED driver to offer integrated temperature compensation for the color LED string, simplifying the design of high color rendering index (CRI) LED lamps. With integrated temperature compensation, you can maintain your desired correlated color temperature (CCT) over the entire LED lamp temperature range. Using the device’s look-up table, programmed in its integrated EEPROM, you can vary the LED string currents to follow the desired CCT compensation curve.
