The Texas Instruments LP5521YQ/NOPB is a versatile 3-channel LED driver designed for RGB and white LED applications. It integrates a charge pump for efficient LED driving, supporting analog/PWM mixed dimming and I2C control for precise lighting effects.
This device operates within a 2.7V to 5.5V input voltage range, delivering up to 25.5mA of constant current per channel. It features internal program memory and programmable ramp control, enabling complex lighting sequences. The LP5521YQ/NOPB is available in a 24-WQFN (5x4) package and is designed for surface mount applications.
Key electrical characteristics include a typical quiescent current of 1.5mA and a low shutdown current of 0.2µA. The device also offers features like power-save mode and programmable lighting engines, making it suitable for various illumination tasks, including backlighting.
With its compact size and integrated charge pump, the LP5521YQ/NOPB minimizes external component count, simplifying design and reducing solution size. Its operating temperature range is -30°C to 85°C.
