LNK419LG from Power Integrations is a highly integrated LED driver IC which features a very precise LED system with wide range dimming. The device also has a high efficiency and low EMI for an ideal LED driver solution for a variety of applications. The LNK419LG is available in either an improved isolated 4-SET flyback configuration or a non-isolated buck configuration. This device can be used for driving both low voltage and high voltage LED strings.
The main application areas of LNK419LG are backlighting and lighting, automotive, industrial and avionics lighting applications. In these application areas, LNK419LG can be used to provide precise, dimmable LED lighting with minimal additional components. The LED driver provides a wide range of dimming options, and it has a low EMI which is ideal for backlighting applications.
The working principle of the LNK419LG is based on a current-mode PWM controller and a diode-bridged buck topology. In the dimming state, the PWM is disabled, and the LED driver is set to the corresponding dimming state by means of analog dimming control. The current-mode controller monitors the output current, and adjusts the duty cycle of the inductor in order to maintain the desired output current. This also ensures a robust and stable dimming state.
By using the LNK419LG, designers can easily set the outputs of LEDs accurately and precisely. The device is also highly efficient and has low EMI, making it suitable for a wide range of backlighting and lighting applications. The LNK419LG has been designed to meet various industry standards, and it is available in a number of packages, making it very easy to integrate into a variety of systems. The LNK419LG is an ideal solution for LED drivers, providing accurate and reliable dimming for a variety of LED applications.
