The LP8552TLE/NOPB is a high-efficiency, mid-power, programmable LED driver designed by Texas Instruments. This LED driver is optimized for powering the backlight of LCD panels, which are commonly used in notebook computers, monitors, and various other display devices. The LP8552TLE/NOPB is well-suited for applications that require precise illumination control, energy efficiency, and a compact form factor.

Key Features

• High-Efficiency Boost LED Driver with Integrated FET
• Programmable Switching Frequency (up to 1MHz)
• Adaptive Output Voltage for Power Savings
• EEPROM for Content Programming and Storage
• Phase Shift PWM Dimming to Reduce Audible Noise
• Protection Features: Overvoltage, Undervoltage, Overtemperature, and Short-Circuit
• Compliant with RoHS and Green Product Requirements (NOPB: No Lead)

Performance and Flexibility

The device's ability to program the switching frequency up to 1MHz allows for flexibility in design, enabling the selection of smaller external components and reduction of overall solution size. The LP8552TLE/NOPB provides excellent power efficiency by adapting the output voltage to the LED load's requirements, thereby reducing power loss.

Intelligent Control

With its integrated EEPROM, the LP8552TLE/NOPB allows designers to program and store specific configurations for the LED driver, which can be tailored to the needs of the application. The phase shift PWM dimming feature is particularly useful in applications sensitive to noise as it can minimize the audible noise that often accompanies PWM dimming.

Safety and Environmental Compliance

Safety is a primary concern in the design of electronic components. The LP8552TLE/NOPB incorporates several protection features to ensure reliable operation under various conditions. These include overvoltage, undervoltage, overtemperature, and short-circuit protection. Additionally, the NOPB designation indicates that this product is lead-free and complies with RoHS standards, making it a more environmentally friendly choice for electronic manufacturers.
