LM2754SQX/NOPB

Overview

The LM2754SQX/NOPB is an LED lighting driver IC designed for switched capacitor flash LED applications. It provides a maximum output current of 800 mA and features four independent outputs. The device operates within a supply voltage range of up to 5.5 V and supports a wide operating temperature range from -40°C to +85°C. Packaged in a 24-pin WQFN (WQFN-24) surface-mount package, it integrates time-out protection mechanisms to ensure safe operation during high-current flash events.

Feature Summary

Integrated time-out protection for enhanced safety during flash operations
Switched capacitor architecture for efficient power delivery
Four-channel output capability for multi-LED configurations

Applications

Smartphone camera flash systems
Mobile device illumination modules
Compact electronic flash units

Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when sourcing. Confirm the NOPB designation ensures compliance with RoHS standards and absence of lead/tin plating where applicable. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high peak current in space-constrained mobile applications. The WQFN-24 package offers a compact footprint suitable for dense PCB layouts. Ensure input voltage capabilities align with the system's battery or power rail specifications to maintain optimal efficiency and thermal performance under continuous load conditions.

Part Context

This part belongs to the LM2754 family of LED drivers from Texas Instruments. It is specifically engineered for portable consumer electronics where size and efficiency are critical. The SQX variant denotes the specific tape-and-reel packaging configuration, distinguishing it from cut-tape or bulk options while maintaining identical electrical characteristics and functionality.
