The L6520 is a versatile, integrated lighting controller designed primarily for use in AC-DC and DC-DC LED drivers. The IC provides an accurate current control loop and is capable of dimming LED lighting at line frequency while providing an efficient, high-side LED driver with a comprehensive protection system. The L6520 is a high-performance, pre-programmed IC designed to provide precise current control of LED lighting systems at higher power levels. It is perfect for applications where dimming is desired for precision levels. With its tight control loop, the L6520 can ensure high accuracy of the set current throughout the input voltage range. In addition to precise current regulation, the L6520 offers two synchronizable dimming modes, pulse-width modulation (PWM) and pulse frequency modulation (PFM), providing high resolution and linear dimming. This enables users to create dynamic dimming control systems for enhanced aesthetic appeal and greater customer satisfaction. Furthermore, the L6520 is built with extensive protection features, including over-current protection, open loop protection, and thermal shutdown protection, providing an added layer of protection for the LED lighting system. The L6520 is designed to provide efficient and accurate lighting control. It contains a high-side driver that can be regulated through the use of an adjustable current sense resistor to accurately control the current in the LED system. It also includes an OVP (over voltage protection) and a temperature monitoring circuit to prevent LED failures caused by over-heating. Moreover, protection features are integrated to ensure safe operation during inadvertent faults.Finally, the L6520 has been designed for stringent EMC compliance, ensuring its compatibility with EMI (electromagnetic interference) regulations. This allows it to be used in environments where other traditional designs may not be suitable. In summary, the L6520 is a high-performance, integrated LED lighting control IC that is perfect for use in AC-DC and DC-DC LED drivers. It offers an accurate current control loop and two synchronizable dimming modes that enable dynamic dimming control systems to be created. It is also designed to provide an efficient, high-side LED driver with a comprehensive protection system to ensure safe operation. In addition, the L6520 contains a number of EMC compliance features, making it suitable for use in environments where traditional designs may not be suitable.
