LM3535 Multi-Display LED Driver with Ambient Light Sensing and Dynamic Backlight Control Compatibility August 12, 2010 LM3535 Multi-Display LED Driver with Ambient Light Sensing and Dynamic Backlight Control Compatibility General Description The LM3535 is a highly integrated LED driver capable of driving 8 LEDs in parallel for large display applications. Independent LED control allows for a subset of the 6 main display LEDs to be selected 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. The LED driver current sinks are split into three independently controlled groups.
