LEDs (Light Emitting Diodes) are an alternative source of light that is becoming increasingly popular for interior and exterior lighting applications due to their improved energy efficiency, long lifetime and environmental friendliness. LYT3314D is a high efficiency, high power LED driver that is specifically designed for the purpose.

LYT3314D is a high-performance, multi-channel constant current driver offering up to 3 independent channels of up to 100mA per channel. It is designed to meet the increasingly stringent efficiency requirements of efficient AC-DC power supplies. It offers integrated power management functions, including over-temperature protection, over-voltage protection and over-current protection, as well as EMC optimized architecture.

The LYT3314D can be used in a variety of lighting applications, such as outdoor lighting, flood lighting, street lighting, and tunnel lighting. It is also suitable for automotive and other automotive related applications, such as automotive interior lighting, automotive exterior lighting and automotive indicator lighting. Additionally, the LYT3314D can also be used in a variety of applications requiring constant current regulation, such as backlight dimming, LCD/LED monitor dimming and digital light processing (DLP) systems.

LYT3314D is a full bridge three-channel constant current driver that can achieve up to 80% efficiency, making it well suited for achieving the stringent efficiency requirements of 80 PLUS certification. It supports adjustable current regulation from 5mA to 100mA per channel and can output up to 300mA in total. The precision of the output current is ±5%, and the rate of change in output current is 0.2mV/mA. This ensures a highly efficient and stable LED lighting module that meets the stringent requirements of 80 PLUS certification.

The LYT3314D is designed to be an intelligent LED driver; in addition to the features mentioned above, the driver also features integrated intelligence, such as the ability to dim the LED output (inversely proportional to the input voltage) and to sense the amount of ambient light and automatically adjust the LED output. It also features a comprehensive thermal protection system, with over-temperature and over-voltage protection and adjustable thermal shut-down.

The LYT3314D LED driver offers reliable performance and high efficiency in both AC-DC and DC-DC applications due to its integrated power management functions and EMC optimized architecture. It is also suitable for use in a variety of lighting applications and those requiring constant current regulation, such as LCD/LED monitor dimming and DLP systems. As the drive is packaged in a small QFN package, it is well suited for use in space-saving applications.
