LM3500TL-16/NOPB

Overview

The LM3500TL-16/NOPB is a synchronous step-up DC/DC converter designed for white LED applications. It operates within a supply voltage range of 2.7V to 7V and supports an output current of up to 400mA per channel. The device features a fixed switching frequency and includes integrated protection mechanisms such as overcurrent limiting and thermal shutdown. It is housed in an 8-pin DSBGA package, suitable for surface-mount assembly.

Feature Summary

• Synchronous step-up topology for efficient white LED driving
• Integrated analog dimming control capability
• Built-in overcurrent and thermal protection circuits

Applications

• White LED backlighting systems
• Portable electronic device illumination
• Battery-powered lighting modules

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the 'TL' variant designation matches the required pinout and thermal characteristics for your PCB layout. Ensure the DSBGA package dimensions align with your assembly capabilities.

Selection Notes

Select this component when a compact synchronous boost converter is needed for single or dual white LED strings. Consider the 400mA output limit and input voltage range relative to the battery source. Evaluate the DSBGA package size constraints against available board space and thermal dissipation requirements.

Part Context

This part belongs to the LM3500 series of LED drivers from Texas Instruments. It is functionally similar to the LM3500TLX-16 but may differ in packaging or environmental compliance specifications. The series is designed for portable applications requiring high efficiency and small form factor solutions.

Replacement Considerations

Publicly confirmed substitutes include LM3500TLX-16/NOPB. Verify pin compatibility and electrical parameters before substitution.
