LM3500TLX-16/NOPB

Overview

The LM3500TLX-16/NOPB is a synchronous step-up DC/DC converter designed for white LED applications. It features an input voltage range of 2.7V to 7V and supports up to five series-connected LEDs. The device delivers a regulated output current of 400mA with a switching frequency of 1MHz. It operates within a temperature range of -40°C to +85°C and utilizes an 8-pin DSBGA package.

Feature Summary

Synchronous rectification for high efficiency
Constant current regulation for LED driving
Supports multiple series white LEDs

Applications

White LED backlighting
Portable electronic displays
General LED illumination systems

Procurement Notes

Verify the specific suffix '16' against the latest Texas Instruments datasheet to confirm pinout and electrical specifications. Ensure the DSBGA-8 package footprint matches the target PCB design. Check component status as some sources indicate obsolescence; confirm availability through authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when a compact, high-efficiency boost converter is required for driving multiple white LEDs from a single-cell lithium battery or similar low-voltage source. The integrated synchronous rectifier reduces external component count. Verify that the 400mA output current aligns with the LED array requirements and thermal constraints of the application.

Part Context

This part belongs to the LM3500 family of LED drivers from Texas Instruments. It is functionally related to the LM3501 but differs in specific configuration parameters. The device replaces older National Semiconductor designs, maintaining compatibility with existing LED driver architectures while offering improved integration and efficiency in a small surface-mount package.

Replacement Considerations

LM3500TLX-16/NOPB is marked as obsolete in several databases. Consider the LM3500TLX-16 if available, though it may share the same end-of-life status. No direct active replacement is confirmed in public documentation; consult Texas Instruments for current portfolio alternatives.
