LM3533TMX-40/NOPB

LED Driver IC Overview

The LM3533TMX-40/NOPB is a regulated LED driver IC from Texas Instruments, designed for high-efficiency white LED applications. It integrates a DC-DC regulator with boost and switched-capacitor (charge pump) topologies to drive up to seven output channels. The device supports PWM dimming control and operates within a supply voltage range of 2.7V to 5.5V. It delivers an output current of 30mA per channel and can generate output voltages up to 40V. Operating frequencies are selectable at 500kHz or 1MHz. The component is housed in a 20-DSBGA package and is rated for a junction temperature range of -40°C to 125°C.

LED Driver IC Feature Summary

Integrates dual topology architecture combining boost converter and charge pump capabilities for flexible LED driving configurations.
Supports multi-channel regulation with independent control for up to seven LED strings.
Enables precise brightness control through integrated PWM dimming functionality.
Features internal power switches to minimize external component count and board space.

LED Driver IC Applications

Backlighting systems for mobile devices
White LED lighting drivers
Portable electronic display illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'TMX' indicates tape-and-reel packaging when sourcing. Confirm that the '-40' designation aligns with the required extended industrial temperature range specifications for your application environment. Ensure compatibility with the 20-DSBGA footprint during PCB layout verification.

LED Driver IC Selection Notes

Select this component when designing circuits requiring multiple LED channels driven by a single regulator. Consider the 30mA output limit per channel against total load requirements. Evaluate the 500kHz/1MHz frequency options based on inductor size constraints and efficiency targets. Verify input voltage stability within the 2.7V to 5.5V window.

LED Driver IC Part Context

This part belongs to the LM3533 family of LED drivers from Texas Instruments. It shares core regulatory features with variants like the LM3533TME-40/NOPB but differs primarily in packaging configuration. The series is engineered for compact portable electronics where space efficiency and thermal performance are critical design parameters.
