LM2756TMEV
| Multi-Display Inductorless LED Driver with 32 Exponential Dimming Steps in micro SMD | Full production
|
| $100.00 each | 1 |
| 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.).
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 I 2C Compatible Interface
- Up to 90% Efficiency
- Total Solution Size <21mm2
- Low Profile 20 Bump micro SMD Package (1.615mm x 2.015mm x 0.6mm)
- 0.4% Accurate Current Matching
- Internal Soft-Start Limits Inrush Current
- True Shutdown Isolation for LEDs
- Wide Input Voltage Range (2.7V to 5.5V)
- Active High Hardware Enable
Applications:
- Dual Display LCD Backlighting for Portable Applications
- Large Format LCD Backlighting
- Display Backlighting with Indicator Light
