LP55231SQE/NOPB Description

Short technical summary and product information.

The Texas Instruments LP55231SQE/NOPB is a versatile 9-channel LED driver designed for RGB and white LED applications. This device integrates internal program memory and a charge pump, enabling efficient and flexible LED control.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V and a maximum LED current per channel of 25.5mA. The driver supports PWM dimming for precise light control and features a charge pump topology for high efficiency, reaching up to 94% for the charge pump and 93% for LED drive.

 

Operating within a temperature range of -30°C to 85°C, the LP55231SQE/NOPB is suitable for various environmental conditions. It offers a typical quiescent current of 0.8mA and a low shutdown current of 0.2µA, contributing to power-saving modes. The device is available in a 24-WQFN (4x4) package, designed for surface mounting.

 

With features like analog/PWM mixed dimming, constant current control, and an I2C-compatible interface, this LED driver provides programmable lighting engines and flexible instruction sets. It also includes overcurrent and short-circuit protection, along with a built-in LED test function.
