PMIC - LED Drivers: AL9910-5S-13

AL9910-5S-13 is a linear current-controlled constant current LED driver integrated with a MCU, specially designed for the entertainment lighting applications. It is manufactured by American Bright Optoelectronics Corporation (ABOC) and is capable of driving up to five 10W LEDs with an accurate current output and is highly efficient, providing power savings compared to other LED drivers. This LED driver is designed to provide a wide range of adjustable current output options for various scenarios, and it can also be used for dimming purposes.

Application Fields

The AL9910-5S-13 LED Driver is mainly used in the entertainment lighting applications, such as architectural, stage and studio lighting, event lighting, and LED signage systems. This LED driver is also well-suited for decorative lighting products such as RGB LED strips, LED spotlights, and LED floodlights. The wide range of adjustable output current options make it ideally suited for driving a variety of LED lights, and its small form factor makes it suitable for applications in confined spaces.

Working Principle

The AL9910-5S-13 LED driver works by controlling the current flow in each LED connected with it. It receives the PWM signal from the controlling host i.e. the MCU, and it converts it into the linear, continuous current. The MCU sends the PWM signal to the AL9910, and the AL9910 modulates the current output by adjusting the switching frequency of its internal MOSFETs. This enables precise control of the current flow, achieving high efficiency and precise dimming control.

The AL9910-5S-13 also features over-temperature protection, over-current protection and short-circuit protection to ensure safety and reliability. In case the operating temperature of the LEDs reached the maximum limit set by the user, the AL9910-5S-13 will limit the current output to prevent any further damage. In case of an over-current or a short circuit, the AL9910-5S-13 will shut down immediately to protect the connected LEDs.

Conclusion

The AL9910-5S-13 is a powerful and efficient LED driver, designed especially for the entertainment lighting applications. It is capable of accurately controlling the current output to fit various scenarios and is also highly reliable and safe. It provides power savings, high efficiency, and precise dimming control, making it the ideal choice for organizations seeking to optimize their energy utilization.
