Overview
The LM2751SD-A/NOPB is a regulated switched capacitor white LED driver manufactured by Texas Instruments. It operates with an input voltage range of 2.8V to 5.5V and provides a maximum output current of 150mA. The device utilizes a charge pump topology to drive LEDs, supporting a maximum output voltage of 4.5V. It functions at a constant operating frequency of 725kHz. The component is housed in a WSON-10 package and is rated for operation between -40°C and +85°C.
Feature Summary
- Regulated switched capacitor architecture for stable LED driving
- Integrated dimming control capability
- Low input and output voltage ripple design
Applications
- White LED lighting systems
- Portable electronic device illumination
- Backlighting applications
Procurement Notes
Verify the specific suffix 'A' against the official Texas Instruments datasheet to confirm exact electrical characteristics and pinout compatibility. Ensure the WSON-10 package dimensions match the target PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.
Selection Notes
Select this component when a compact, single-output LED driver is required for low-voltage applications. The fixed 725kHz switching frequency aids in EMI management compared to variable frequency alternatives. Consider the 150mA current limit and 4.5V output ceiling to ensure alignment with the specific LED string configuration and power supply constraints of the design.
Part Context
This part belongs to the LM2751 series of LED drivers from Texas Instruments. It shares the core switched capacitor technology with variants like the LM2751SD-B/NOPB but may differ in internal trim settings or packaging options. The series is designed for efficient white LED regulation in space-constrained portable devices.
Replacement Considerations
The LM2751SD-B/NOPB is a documented variant within the same family. Verify if the 'A' suffix denotes a specific binning or revision that requires distinct handling compared to the standard B version.
