LM2756 Multi-Display Inductorless LED Driver with 32 Exponential Dimming Steps in micro SMD December 5, 2007 LM2756 Multi-Display Inductorless LED Driver with 32 Exponential .. Dimming Steps in micro SMD General Description The LM2756 is a highly integrated, switched-capacitor, multidisplay LED driver that can drive up to 8 LEDs in parallel with a total output current of 180mA. Regulated internal current sources deliver excellent current and brightness matching in all LEDs. The LED driver current sinks are split into three independently controlled groups. The primary group (Group A) can be configured to drive four, five or six LEDs for use in the main phone display,...
