LP5521YQX/NOPB Description

Short technical summary and product information.

The Texas Instruments LP5521YQX/NOPB is a versatile 3-channel LED driver designed for RGB and white LED applications. It utilizes a charge pump topology for efficient operation and supports I2C control for precise dimming and configuration.

 

This device operates with an input voltage range of 2.7V to 5.5V and can deliver up to 25.5mA per channel. Key features include programmable ramp control, internal program memory, and a shutdown current of only 0.2µA typical. The driver is suitable for backlight applications and offers mixed analog/PWM dimming capabilities.

 

Packaged in a 24-WQFN (5x4) format, the LP5521YQX/NOPB is designed for surface mount installation. Its compact size and integrated charge pump eliminate the need for external inductors or resistors, simplifying board design and reducing solution size. The operating temperature range is -30°C to 85°C.
