LP5521TMX/NOPB

LED Driver IC Overview

The LP5521TMX/NOPB is a Texas Instruments LED lighting driver IC featuring three independent output channels designed for RGB or White LED applications. It integrates an internal charge pump topology to regulate current, supporting a supply voltage range of 2.7 V to 5.5 V with a maximum output current of 25.5 mA per channel. The device operates at a switching frequency of 1.25 MHz and includes I2C control interfaces for configuration. It is housed in a 20-TuSMD (DSBGA-20) package and functions within a temperature range of -30°C to +85°C.

LED Driver IC Feature Summary

• Integrates internal program memory for autonomous operation without external microcontrollers.
• Supports mixed analog and PWM dimming methods for precise brightness control.
• Features integrated charge pump circuitry for efficient LED driving.
• Includes power save mode functionality to optimize energy consumption.

LED Driver IC Applications

• LED backlighting systems
• RGB indicator lighting
• White LED illumination modules

LED Driver IC Procurement Notes

Verify the specific ordering suffix matches the required package variant and tape/reel specifications. Confirm that the component complies with RoHS3 standards and REACH regulations for your target market. Ensure the I2C address configuration aligns with your system design requirements before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when a compact solution for multi-channel LED control is required. It is suitable for designs needing integrated charge pump capabilities to drive LEDs efficiently from low-voltage sources. Consider the 20-pin DSBGA footprint constraints and thermal management needs during the PCB layout phase.

LED Driver IC Part Context

This part belongs to the LP5521 series of programmable LED drivers from Texas Instruments. It is distinct from higher-channel variants like the LP5523, which offers nine outputs. The LP5521 focuses on providing efficient control for smaller arrays or single RGB pixels with integrated memory features.
