LP5521TM/NOPB Description

Short technical summary and product information.

The Texas Instruments LP5521TM/NOPB is a versatile 3-channel LED driver designed for applications requiring precise control of RGB and white LEDs. It features an integrated charge pump, enabling efficient LED drive with a typical output current of 25.5mA per channel. The device operates from an input voltage range of 2.7V to 5.5V.

 

Control is managed via an I2C-compatible interface, allowing for flexible dimming and lighting effects. The LP5521TM/NOPB supports analog/PWM mixed dimming and includes programmable lighting engines with internal program memory. Its topology is a switched capacitor (charge pump), and it includes features like constant current and current control.

 

Packaged in a 20-TuSMD (20-WFBGA) surface mount configuration, this LED driver is suitable for compact designs. The operating temperature range is -30°C to 85°C. Key features include a quiescent current of 1.5mA and a shutdown current of 0.2µA, contributing to power efficiency.
