LP5520TLX/NOPB is a PWM controller for RGB or white LEDs, or RGBW LEDs if used with 4 drivers instead of 3. It is capable of driving up to 18 channels and can perform 5 types of lighting modes, allowing the construction of very elaborate lighting effects. The LP5520TLX/NOPB is used in many consumer electronic devices with backlighting and/or decorative lighting and has a number of applications ranging from smart devices, automotive lighting, and home lighting.

Application field

LP5520TLX/NOPB is a very versatile LED driver that is used in consumer electronics applications such as smart devices, LED backlighting, LED decorative lighting, automotive applications, and many other fields. It is especially suitable for standard RGB LED systems, RGBW LED systems, and single-color LED systems.

In consumer electronics applications, the LP5520TLX/NOPB is often used for LED backlighting. LEDs are relatively expensive, however, so the LP5520TLX/NOPB can provide an intuitive way to adjust the brightness of the backlighting with simple pulse-width modulation (PWM). This can also be used in decorative lighting applications, where the LED driver is used to create elaborate lighting effects.

In automotive applications, the robustness and efficiency of the LP5520TLX/NOPB makes it an ideal choice for LED backlighting and turn signals. The LED driver is also capable of driving high power LEDs that are used in headlights and fog lamps. As automotive lighting systems become more complex, the LP5520TLX/NOPB is becoming increasingly popular for powering multiple LEDs in synchronization.

LP5520TLX/NOPB is also being used in home lighting applications, where its high efficiency and low power consumption make it an ideal choice. The LP5520TLX/NOPB can be used to create different lighting effects, such as dimming, flashing, fading, and so on. This makes it ideal for mood lighting and energy efficient lighting applications.

Working principle

The LP5520TLX/NOPB uses pulse-width modulation (PWM) to provide accurate, repeatable adjustments to the brightness of the LEDs it is driving. This is achieved by rapidly switching the LED’s current on and off in order to produce an average value of the total current. By varying the width of the on/off pulses, the overall brightness of the LEDs can be adjusted.

LP5520TLX/NOPB can be used to drive up to 18 channels simultaneously, allowing for greater flexibility in creating complex lighting effects by controlling multiple LEDs. The LED driver also includes five types of lighting modes, these are static (constant brightness), breathing (fade in and fade out), flashing (periodically on and off), pulse (jumping brightness) and gradient (smooth transition). All these effects can be achieved with the appropriate setting of the LED driver.

In addition, the LP5520TLX/NOPB also features short-circuit, overtemperature and undervoltage protection, which ensures the safety of the LEDs and prevents them from being damaged by power surges or excessive heat. Additionally, the LED driver features an integrated programmable timer, allowing for precise control over the timing of lighting effects.

The LP5520TLX/NOPB has therefore proven to be a reliable and efficient LED driver for a variety of applications. Its wide range of features and capabilities make it an ideal choice for consumer electronics applications, automotive lighting and home lighting.
