Introduction
The LP5520TL/NOPB device is a highly integrated, easy-to-implement, and programmable LED driver from Texas Instruments. It provides output current control and adjustable output current accuracy for up to four independent LED strings, allowing a wide range of LED strings and applications. The LP5520TL/NOPB can also be configured to either drive high-brightness LED strings or single LED strings with pulse-width-modulation dimming. This highly integrated LED driver is specifically designed to provide a wide variety of LED applications in different packages, while also delivering extremely low-cost and low-power solution solutions.

Application Field
The LP5520TL/NOPB provides a wide range of LED applications, including: low-power displays, automotive, medical and consumer applications. Low-power displays include e-readers and connected devices, such as smartphones and notebooks. Automotive applications provide illumination for automotive interiors, as well as exterior lighting designs. Medical applications range from interval lighting for operating rooms to lighting for patient care areas. Consumer applications range from light strings to backlighting LCD displays.

Operation Principle
The LP5520TL/NOPB uses a simple and intuitive setup, providing adjustable current control, resulting in excellent color accuracy. The device also provides four control-mode options: parallel mode, pulse-width-modulated mode, brightness-mode and programmable-brightness mode. Parallel mode allows simple LED enabling and controlling the brightness by varying the LED current. Pulse width modulated mode is used for LED dimming and flicker reduction for LED strings with long-term average brightness stability. Brightness mode is a low-cost, low-power adaptive LED brightness control mode in which the LED current is kept constant, with an adaptive brightness control loop to adjust the LED current to the desired brightness level. Lastly, the Programmable Brightness Mode is a powerful feature of the device, enabling the user to control the LED current of up to four independent LED strings simultaneously.

Protection Features
The LP5520TL/NOPB is equipped with protection features, including short-circuit protection and over-temperature protection, to guard against any potential damage to the device or connected load. The device also has output current-sense protection, which prevents excess current flowing through the device and into the external LEDs.

Conclusion
The LP5520TL/NOPB is an ideal solution for customers looking for a low-cost and highly integrated LED driver with simple and intuitive setup. The device offers a wide variety of applications, including: low-power displays, automotive, medical and consumer applications. It provides a simple and intuitive setup, with adjustable output current control, resulting in excellent color accuracy. The device is also equipped with protection features, such as short-circuit protection and over-temperature protection.
