LM2751SDX-B/NOPB

Overview

The LM2751SDX-B/NOPB is a regulated LED driver IC from Texas Instruments utilizing a switched capacitor (charge pump) topology. It provides a single output with a maximum current of 150 mA and an output voltage of 4.5 V. The device operates within an input voltage range of 2.8 V to 5.5 V at a switching frequency of 725 kHz. It is housed in a WSON-10 package and supports operation temperatures from -40°C to +85°C.

Feature Summary

Integrates a charge pump topology for efficient DC-DC regulation without requiring inductors.
Supports PWM dimming functionality for precise brightness control applications.

Applications

LED backlight drivers
Portable electronic display illumination

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official documentation to confirm functional variations or binning differences. Ensure the WSON-10 package footprint matches the design requirements. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement specifications.

Selection Notes

Select this component when an inductor-less solution is required for low-current LED driving. The charge pump architecture simplifies layout compared to inductive converters. Verify that the 150 mA output capability meets the target LED string requirements and that the 725 kHz frequency aligns with EMI constraints.

Part Context

This part belongs to the LM2751 series of LED lighting driver ICs. It is distinct from the LM2750, which utilizes a boost topology, and the LM27951, which offers adaptive switching capabilities. The LM2751 specifically targets applications requiring a compact, inductor-free power stage for white LED arrays.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's cross-reference tools for potential equivalents based on specific electrical and pinout compatibility requirements.
