The LM3519MKEV is a high performance LED driver, used in various lighting and LED display applications. It is a versatile and efficient LED driver, suitable for a variety of different applications, ranging from domestic lighting to large scale LED display boards. The LM3519MKEV is capable of driving up to 8 LEDs in parallel, making it a great choice for power efficient and visually stunning displays. In this article, we will take a look at the LM3519MKEV\'s application field and working principle.The LM3519MKEV is a high voltage LED driver, capable of driving up to 8 LEDs in parallel with constant current. This makes it ideal for LED power applications, allowing for quicker and safer LED display assembly. The LM3519MKEV also features a wide supply voltage range, ranging from 4V to 42V. This wide range makes the LM3519MKEV a great choice for applications that require multiple power levels, as the driver can handle both low and high power applications. The LM3519MKEV also features a dimming capability, allowing you to adjust the current and intensity of the LEDs. This makes it ideal for applications that require adjustable brightness, such as lighting displays and indications. The LM3519MKEV also features a low operating temperature range, making it suitable for temperature sensitive application. In terms of working principle, the LM3519MKEV uses inductive current regulation, meaning that the current flow is controlled by an inductor. When the load current changes, the inductor\'s stored energy is changed, resulting in a change in the inductor\'s output current, which is then supplied to the LED. In this manner, the inductor creates a constant current flow, regardless of the load variation.The LM3519MKEV also features Thermal Shutdown Protection, which prevents the driver from overheating. This protection will shut down the LED driver, if the temperature rises above the specified level. The shutdown feature will then automatically reset when the temperature falls back within the specified range. Additionally, the LM3519MKEV has a reverse polarity protection, which will protect the unit from damage, when reverse polarity is detected. This feature protects the LED driver from damage, should it be connected with the wrong voltage or current. Overall, the LM3519MKEV is an efficient and versatile LED driver, capable of powering a wide range of applications. It is suitable for both low and high power applications, and features dimming and thermal shutdown protection. The LM3519MKEV is also capable of constant current regulation, making it a great choice for power efficient lighting displays and indications.
