The Texas Instruments LP8550TLE/NOPB is an active, high-efficiency LED backlight driver designed for notebook applications. This device operates with an input voltage range from 2.7V to 22V, supporting 1x to 5x cell Li-ion batteries. It offers 6 LED outputs, each capable of delivering up to 50mA of current.
Key features include adjustable switch frequency with options up to 1250 kHz, programmable PWM resolution from 8 to 13 bits, and I2C and PWM brightness control. The driver also incorporates automatic PWM and current dimming for improved efficiency. It includes LED fault detection for short/open circuits, as well as low input voltage, overtemperature, and overcurrent detection with shutdown capabilities.
The LP8550TLE/NOPB is housed in a 25-uSMD package and supports surface mount installation. Its operating temperature range is -30°C to 85°C. This boost converter with integrated FET is suitable for backlight applications requiring precise LED current control and efficient operation.
