LM3535 Description
The LM3535 device is a highly integrated LED driver capable of driving 8 LEDs in parallel for large display applications. Independent LED control allows selection of a subset of the 6 main display LEDs for partial-illumination applications. In addition to the main bank of 6, the LM3535 is capable of driving an additional 2 independently controlled LEDs to support Indicator applications.
