Overview
The LM2793LD/NOPB is a dual-output DC-DC regulator utilizing switched capacitor charge pump topology. It provides independent current regulation for two LED channels, each capable of delivering up to 16mA. The device supports PWM dimming control and operates within a frequency range of 325kHz to 675kHz. Packaged in a compact 10-WSON (3x3) format with an exposed pad, it is designed for surface-mount applications requiring efficient backlighting power management.
Feature Summary
- Dual-channel independent current regulation for precise LED control
- Integrated switched capacitor charge pump topology for efficient voltage conversion
- Supports PWM dimming interface for dynamic brightness adjustment
Applications
- LCD panel backlighting systems
- Mobile device display illumination
- Portable electronic equipment lighting
Procurement Notes
Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific package marking matches the 10-WSON designation. Ensure compliance with RoHS standards as indicated by the NOPB suffix. Request official datasheets and quality certificates during acquisition to validate performance specifications against original design requirements.
Selection Notes
Select this component when dual-channel low-current LED regulation is required in space-constrained designs. The charge pump topology eliminates the need for external inductors, simplifying layout. Consider the 16mA output limit per channel when sizing for specific LED arrays. The 10-WSON package offers thermal advantages via the exposed pad for improved heat dissipation in dense PCB environments.
Part Context
This part belongs to the LM2793 series of LED drivers from Texas Instruments. It serves as a specialized power management solution for display backlighting, distinct from general-purpose regulators. The device integrates control logic and power switches into a single IC, reducing system complexity compared to discrete solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in verified documentation. Consult Texas Instruments application engineering for potential cross-references based on specific circuit requirements.
