SC443ULTRT Integrated Circuits (ICs)

PMIC – LED drivers are used to provide a steady current or voltage to LEDs or light sources, helping to achieve a desired level of performance and brightness. Often, this involves regulating brightness, as well as dimming or pulsing LED or light sources. Each LED driver stands out in its own right, depending on the application field and its working principle, which helps to give each LED driver its own unique advantages.

The SC443UTLRT is a great example of an LED driver. It belongs to NXP’s ultra-efficient, current-mode (CM) general-purpose LED driver IC, providing an effective and reliable solution for driving LEDs for a variety of applications. This LED driver IC is designed for ease of use, having functions such as automatic thermal protection, dimming switches and a constant current (CC) or constant voltage (CV) configuration, plus several other features.

As mentioned previously, the application field and working principle of the SC443UTLRT helps differentiate it from other LED drivers and gives it unique advantages. As far as its application field, the SC443UTLRT can easily be used in various applications such as indicator lamps, panel illumination, automotive entertainment systems, and many more. There are more than 4,000 NXP products available for controlling LEDs and lighting systems and the SC443UTLRT helps address a wide range of needs.

As for its working principle, the SC443UTLRT LED driver IC employs a high-efficiency, current-mode, step-up DC/DC converter. Its integrated linear current regulator provides a constant loop current with a minimum of 300 mA and up to 500 mA. Its integrated 60V N-Channel MOSFET can deliver up to 20W of power, allowing it to support the delivery of currents to a wide range of medium and large LEDs.

In addition to its general purpose current mode and high efficiency, the SC443UTLRT has a wide input voltage range and extended LED voltage. It can easily be used in applications that require a wide input range in order to take advantage of an increase in brightness over a range of LED string voltages. In these applications, the IC’s extended LED voltage increases available LED voltage range, allowing it to drive up to eight LEDs in series for optimal lighting performance.

One of the best features of the SC443UTLRT is its low-voltage operation capability. It operates from a single supply of 6V and its internal current-mode control circuit allows it to run at very low input voltages. This feature is especially useful in lighting applications where low-voltage sources are being used, such as battery-operated equipment and wearable electronics.

Overall, the SC443UTLRT LED driver IC is one of the most efficient and reliable currently offered by NXP. It offers a wide range of features, offering an array of benefits to users in need of a high-performance LED driver. By taking advantage of its application field and working principle, the SC443UTLRT can provide an effective and reliable solution for driving LEDs in a wide range of applications, allowing it to meet even the most demanding customer requirements.
