ALED1642GWXTTR, a PMIC (Power Management Integrated Circuit) - LED (Light Emitting Diode) Drivers, is widely applied in various electronic products for providing signals for controlling the amount of current to drive LEDs. As a highly integrated and reliable solution that supports up to 16 LEDs, this driver integrates high-voltage switching buck converters and capable of managing the brightness of LEDs. As a buck driver, ALED1642GWXTTR can save a considerable amount of energy when compared to the traditional linear current regulator, as it can step down the input voltage to a lower level.

Working Principle:

ALED1642GWXTTR contains two voltage buck converters with a maximized DC/DC efficiency. During the conversion process, the two buck converters can produce two supliments, one with a voltage drop of 2V to support LED lighting, and one with a standard 20V-25V drop for normal LED applications. The controller will adjust the output current of the step-down converters according to the control signal sent from the host, thereby controlling the brightness of the LED. In order to protect the LED from excessive current and thermal issues, the ALED1642GWXTTR series buck drivers are designed with an over temperature protection, short circuit protection and over voltage protection.

Application Field:

ALED1642GWXTTR LED drivers belong to PMIC - LED Drivers, and they can be applied in optoelectronic products, such as LED lightings, LCD displays and backlight modules. As a highly integrated and reliable solution, this LED driver offers great accuracy and excellent power efficiency, making it ideal for medium and high power LED applications. This series of LED driver can not only be used for simple lighting effects, but also can be used for complex, context-sensitive illumination such as RGB LEDs, enabling different RGB color combinations. On top of that, they also provide thermal and power management functions, which ensures that the LED lighting system is running stably and efficiently.

In conclusion, with its controller, built-in high-voltage switching buck converters and other features, ALED1642GWXTTR is a highly integrated and reliable PMIC - LED Drivers that is versatile for all kinds of optoelectronic products. It can easily provide a wide range of color changing, brightness changing and other complex functions without compromising the system’s power and thermal stability.
