LM3508TLX/NOPB

LED Driver IC Overview

The LM3508TLX/NOPB is a synchronous magnetic constant current LED lighting driver IC manufactured by Texas Instruments. It utilizes a boost topology to regulate output current for single-channel applications. The device operates within an input voltage range of 2.7 V to 5.5 V and supports a maximum output voltage of 17.5 V. Key electrical parameters include a fixed operating frequency of 850 kHz, a maximum output current of 30 mA, and a maximum supply current of 500 uA. It is housed in a DSBGA-9 package and functions reliably across a temperature range of -30°C to +85°C.

LED Driver IC Feature Summary

• Synchronous magnetic constant current regulation for precise LED control
• Integrated PWM dimming capability for brightness adjustment
• Fixed high-frequency operation at 850 kHz

LED Driver IC Applications

LED Driver IC Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence as per manufacturer documentation. Confirm the DSBGA-9 package type matches your PCB footprint requirements. Ensure the input voltage range aligns with your system's power supply specifications before integration.

LED Driver IC Selection Notes

Select this component when a compact solution for low-current LED driving is required. The boost topology is suitable for applications where the LED forward voltage exceeds the supply voltage. Consider the 850 kHz switching frequency for inductor size trade-offs and the 30 mA output limit for appropriate LED string configurations.

LED Driver IC Part Context

This part belongs to the LM3508 series of LED drivers from Texas Instruments. It is designed specifically for portable applications requiring efficient, space-saving LED control. The device integrates the necessary power switches and control logic into a small form factor, distinguishing it from discrete solutions or larger driver packages.

LED Driver IC Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence if considering cross-references from other manufacturers.
