LM2756 - Multi-Display Inductorless LED Driver

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.

Key Features

  • Drives up to 8 LEDs with up to 30mA of Diode Current Each.
  • 32 Exponential Dimming Steps with 800:1 Dimming Ratio.
  • for Group A (Up to 6 LEDs) 8 Linear Dimming States for Groups B (Up to 3 LEDs) and D1C (1 LED) Programmable Auto-Dimming Function 3 Independently Controlled LED Groups Via I2C Compatible Interface Up to 90% Efficiency Total Solution Size < 21mm2 Low Profile 20 Bump micro SMD Package (1.615mm × 2.015mm × 0.6.
