ALED7707

The ALED7707 is a high-efficiency, cost effective, PMIC-LED driver designed for high-brightness LED applications. It is designed to support applications such as automotive, consumer, industrial, and general lighting. The device offers up to 2A output current and up to 600V max input voltage that allows a wide variety of power sources. Additionally, it includes a low startup voltage and comes in either a 6-pin SOT23 package or in a 10-terminal DFN package. Furthermore, the device is rated to operate up to 85°C and offers safety protection features including authentication and over-voltage protection.

The ALED7707 can control the current from two independent current channels, enabling the output current of each channel to be individually varied according to the user’s design. This allows for effective performance optimization. In addition, the driver has built-in dimmable soft-start and current matching functions, providing an optimized power supply design. The device also includes an intelligent overload protection feature that monitors thermal conditions over temperature, and will shut down to protect the LED against overheating.

The ALED7707 works by converting a high voltage input into a regulated current output, while meeting stringent efficiency requirements. The device contains a buck-boost stage that is used to provide the regulated output current, while an integrated PWM controller is used to regulate the buck-boost stage. The maximum input voltage can be set by an external resistor and any voltage up to 600V can be regulated by the device. The output current is regulated by the user-set reference current and can be as high as 2A.

The ALED7707 is a robust and cost effective PMIC-LED driver that provides high efficiency in a wide variety of lighting applications. It features a low startup voltage and programmable input voltage, as well as integrated soft-start, overload protection and current matching. By integrating all of these features, the device provides an optimized power supply design and improved system performance. Also, the ALED7707 is rated to operate up to 85°C, making it suitable for use in extreme temperatures. All of these features make the ALED7707 a great choice for high-brightness LED applications.
