Overview
The LM2756TMX/NOPB is a multi-display inductorless LED driver manufactured by Texas Instruments. It features an I2C control interface and supports up to eight output channels. The device operates within an input voltage range of 2.7 V to 5.5 V, delivering a maximum output current of 180 mA per channel. It utilizes a boost topology with a switching frequency between 1 MHz and 1.6 MHz. The component is housed in a DSBGA-20 package and functions reliably across a temperature range of -30 °C to +85 °C.
Feature Summary
- Supports multi-display configurations with independent channel control
- Integrates I2C digital interface for precise dimming management
- Eliminates external inductors through integrated power stage design
Applications
- LED backlight drivers for mobile devices
- Multi-zone LED lighting systems
- Portable electronic display illumination
Procurement Notes
Verify the specific suffix 'X' indicates tape-and-reel packaging configuration distinct from standard reel formats. Confirm RoHS compliance status matches current manufacturing standards. Ensure the DSBGA-20 footprint aligns with PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when designing compact LED systems requiring multiple independent outputs without inductors. The I2C interface enables flexible brightness control suitable for complex display applications. Verify that the 180 mA output capability meets the specific LED string current requirements for the target design.
Part Context
This part belongs to the LM2756 series of inductorless LED drivers designed for space-constrained portable electronics. It provides a high-density solution for driving multiple LED strings in displays. The NOPB designation confirms lead-free and halogen-free construction compliant with environmental regulations.
Replacement Considerations
LM2756TM/NOPB serves as a direct pin-compatible alternative differing primarily in packaging format rather than electrical performance characteristics.
