LM2751SD-A

Overview

The LM2751SD-A is a regulated switched capacitor white LED driver from Texas Instruments. It operates with an input voltage range of 2.8V to 5.5V and provides a constant frequency charge pump topology. The device supports 2X and 1.5X voltage conversion ratios for driving white LEDs. It features low input and output voltage ripple, ensuring stable performance. The component is housed in a 10-pin WSON package and is designed for efficient LED illumination applications within specified thermal limits.

Feature Summary

Regulated switched capacitor architecture for white LED driving
Supports 2X and 1.5X voltage conversion topologies
Low input and output voltage ripple characteristics

Applications

White LED lighting systems
Portable electronic device illumination
Battery-powered LED drivers

Procurement Notes

Verify the specific suffix 'A' against current manufacturer catalogs, as availability may vary. Confirm RoHS compliance status and packaging options such as cut tape or reel directly with authorized distributors. Ensure the part number matches the exact revision required for your design, as obsolete statuses can impact long-term supply chain stability.

Selection Notes

Select this component when a compact solution for driving white LEDs from a single-cell lithium battery or similar low-voltage source is required. The 10-WSON package offers space efficiency. Consider the 2X and 1.5X gain options to match LED forward voltage requirements without additional inductors, simplifying the bill of materials compared to inductive boost converters.

Part Context

The LM2751 belongs to Texas Instruments' family of LED lighting driver ICs. This series focuses on switched capacitor solutions that eliminate the need for external inductors. The SD-A variant specifically denotes the package type and initial revision within the broader LM2751 product line, targeting cost-sensitive and space-constrained portable lighting designs.

Replacement Considerations

Public records indicate the LM2751SD-A is obsolete. Available substitutes include parametric equivalents or newer revisions such as the LM2751SD-B/NOPB. Verify electrical compatibility and pinout consistency before transitioning to alternative part numbers to ensure circuit functionality remains intact.
