LM3519MKX-20 Application Field and Working Principle

The LM3519MKX-20 is a PMIC (Power Management Integrated Circuit) - LED driver that is designed to be intuitive and energy-efficient. It is one of the most advanced PMIC - LED drivers on the market, providing an efficient way of controlling a wide range of LED applications.The LM3519MKX-20 is an adjustable constant current source that is capable of driving up to 24 LEDs at 350mA. It supports both PWM and digital dimming, providing a wide range of current settings. The constant current output can be set to any value between 0 and 10 watts, so it is ideally suited for controlling a variety of LED applications, including indication, lighting, and RGB-Backlighting.The LM3519MKX-20 is packaged in a small outline integrated circuit (SOIC) package, making it easy to integrate into a design. It also has a low quiescent current, meaning it draws minimal power even when not in use.The LM3519MKX-20 has two inputs; an analog input and a digital input. The analog input is configured using a resistor divider, and can be used to set the current from 0 up to 10 watts. The digital input can be used to control the brightness of the LED, as well as to enable or disable the device.The LM3519MKX-20 also has two output options: a linear-mode output and a direct-out mode output. The linear-mode output provides a more accurate and precise current control, while the direct-out mode output allows the user to control the brightness of the LEDs more quickly and easily.The LM3519MKX-20 also features short-circuit protection, over-temperature protection, and over-current protection. These features help to ensure reliable operation and prevent damage to the device and/or the connected LEDs.The LM3519MKX-20 is a highly efficient and versatile PMIC - LED driver. It is ideal for controlling a wide range of LED applications, including indication, lighting, and RGB-backlighting. Its two output options and adjustable current control make it suitable for a variety of applications. Combined with its small size and low quiescent current, the LM3519MKX-20 is an excellent choice for controlling LED applications.
