LP5018RSMR Description

Short technical summary and product information.

The Texas Instruments LP5018RSMR is an active, 18-channel I2C constant-current RGB LED driver designed for various lighting applications. This linear driver operates within an input voltage range of 2.7V to 5.5V, delivering up to 35mA per channel when the VCC is 3.3V or higher. It features a 12-bit, 29kHz PWM generator for each channel, enabling independent color mixing and brightness control.

 

The device offers ultralow quiescent current, with a typical value of 0.01mA and a shutdown current of 0.2µA. It supports I2C control for easy configuration and includes power-save modes. The LP5018RSMR is available in a 32-VQFN (4x4 mm) package and is suitable for surface mount applications.

 

Key features include device-to-device and channel-to-channel error control, ensuring consistent LED output. The integrated PWM generator allows for optional logarithmic or linear scale brightness control. With its precise current control and flexible interface, the LP5018RSMR is well-suited for applications requiring accurate and dynamic LED illumination.
