What are the key features of LM3503ITL-35?
- Constant-current LED drive at up to 35 V ensures uniform brightness across all 10 LED segments regardless of forward voltage variation
- Non-multiplexed 10-segment output architecture eliminates flicker artifacts present in time-multiplexed LED driver designs
- Ultra-compact 10-ball BGA (PBGA-B10) footprint enables integration into thin portable display backlight modules
- Single-function LED driver reduces system complexity in display backlight circuits with minimal external components
What is LM3503ITL-35 used for?
LM3503ITL-35 is primarily used to drive white LED backlights in small to medium LCD panels found in mobile phones, digital cameras, and portable media players where constant current regulation at up to 35 V is required for uniform illumination. Its 10-segment non-multiplexed output suits multi-LED string applications in consumer electronics backlighting and decorative LED arrays. The compact BGA package makes it ideal for thin-profile handheld devices where board space is extremely limited.

Frequently Asked Questions
What maximum output voltage does LM3503ITL-35 support for driving LED strings?
LM3503ITL-35 supports up to 35 V output, enabling it to drive multiple white LEDs connected in series. A typical series string of 8 white LEDs with 3.3 V forward voltage each totals roughly 26 V, comfortably within the 35 V rating, making this driver suitable for medium-length LED backlights.
How many LED segments can LM3503ITL-35 drive, and does it use multiplexing?
LM3503ITL-35 drives up to 10 LED segments without multiplexing. Non-multiplexed constant-current drive means all 10 channels are active simultaneously, eliminating the brightness reduction and flicker associated with time-division multiplexed designs — important for applications sensitive to visual artifacts.
What package does LM3503ITL-35 use, and what are the implications for PCB assembly?
LM3503ITL-35 is housed in a 10-ball plastic BGA (PBGA-B10). BGA packaging requires reflow soldering and X-ray inspection for quality assurance, but provides a very small footprint — typically under 2 mm x 2 mm — enabling integration into the thinnest handheld device PCBs where leaded packages would not fit.
Is LM3503ITL-35 RoHS compliant, and what does its end-of-life status mean for new designs?
LM3503ITL-35 is not lead-free (JESD-609 code e0, Pbfree Code: No) and has a YTEOL of 0, indicating it is at end-of-life. For new designs requiring RoHS compliance, engineers should evaluate Texas Instruments' current lead-free LED driver portfolio rather than designing in this part, and existing users should secure buffer stock for service needs.
