Description
The LM2756 is a highly integrated, switched-capacitor, multi-display 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 LM2756 is a highly integrated, switched-capacitor, multi-display LED driver that can drive up to 8 LEDs in parallel. The regulated internal current sources on the evaluation boards are set-up to deliver 20mA to each LED delivering excellent current and brightness matching. Utilizing the I 2 C compatible interface, the user can configure the LM2756 evaluation board to drive the eight LEDs in any of the numerous LED group configurations (4:3:1, 5:2:1, 6:1:1, etc.).
