LP55231SQX/NOPB Description

Short technical summary and product information.

The Texas Instruments LP55231SQX/NOPB is a versatile 9-channel LED driver designed for RGB and white LEDs. It features an integrated charge pump topology for high efficiency, reaching up to 94% for the charge pump and 93% for LED drive.

 

This device supports a wide input voltage range of 2.7V to 5.5V, with each of the 9 outputs capable of delivering up to 25.5mA. It offers flexible control through analog/PWM mixed dimming and an I2C-compatible interface. The driver includes features like constant current control, power-save mode, and programmable lighting engines with internal program memory.

 

Packaged in a 24-WQFN (4x4 mm) surface-mount package, the LP55231SQX/NOPB is suitable for applications requiring precise LED control. It also includes built-in protection features such as overcurrent and short-circuit protection, and a typical standby current of 200nA.

 

Key specifications include 8-bit current setting resolution and 12-bit PWM control resolution, along with three independent program execution engines. The operating temperature range is -30°C to 85°C.
