LM3535TMX/NOPB

LED Driver IC Overview

The LM3535TMX/NOPB is a multi-display LED driver IC from Texas Instruments designed for large display applications. It integrates the capability to drive eight LEDs in parallel through independent control channels. The device utilizes a switched capacitor (charge pump) architecture for DC-DC regulation and supports PWM dimming with a specified output current of 25mA per channel. Key functional features include external PWM input for dynamic backlight control and multi-zone ambient light sensing (ALS) with interrupt reporting capabilities.

LED Driver IC Feature Summary

• Integrates independent control for driving multiple LEDs in parallel configurations
• Supports dynamic backlight adjustment via external PWM input signals
• Includes multi-zone ambient light sensing functionality with interrupt reporting

LED Driver IC Applications

• Large display applications requiring parallel LED driving
• Multi-display systems utilizing independent zone control
• Backlight units requiring dynamic brightness adjustment

LED Driver IC Procurement Notes

Verify the specific suffix 'TMX' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements for the internal charge pump. Confirm that the ambient light sensing interface aligns with the host controller's interrupt handling capabilities before finalizing procurement.

LED Driver IC Selection Notes

Select this component when designing systems that require integrated LED driving and ambient light sensing in a single package. It is suitable for applications needing independent control over multiple LED zones without external discrete drivers. Consider the power supply constraints imposed by the switched capacitor topology compared to inductive solutions.

LED Driver IC Part Context

This part belongs to the LM3535 series of multi-display LED drivers. It is distinct from evaluation kits like the LM3533EVAL or other sensor variants such as the LM335 temperature sensors. The device focuses on lighting control integration rather than general-purpose sensing or simple linear regulation.
