Evaluation Boards - LED Drivers

NCV786XXAR20GEVK is a monolithic LED driver support module from the NXP, popular for its design suitability for those companies in LED technology and applications. It is one of the most recent and latest LED drivers that have been rolled out in the market and is widely used. The NCV786XXAR20GEVK module is designed to essentially provide Push-Pull LED dimming control capability in order to extend the dimming functionality of the LED devices on the display along with the digital-analog conversions.

Application Field

NCV786XXAR20GEVK is specialized for driving LEDs in various applications, like energy-efficient lighting, automotive lighting, and general lighting. One of the primary objectives of the module is to provide flexible lighting control and enhanced dimming performance, even with respect to various types of LEDs. The module features a dual 16-bit PWM controller, as well as a dimming current adjuster. It has a dimming range of 200:1 and also offers a per-channel dimmer control for outputting up to 16 channels of connected LEDs. In addition, it also provides brightness control over the LEDs by either controlling the current intensity or the brightness levels individually.Another popular application for the module includes its use for driving the LEDs in automotive dashboard displays. The dashboard displays in the automotive sector generally need to be consistently lit up and therefore, using NCV786XXAR20GEVK module offers constant brightness levels, even during the low power situations. This also helps to reduce the flickering of the light and hence improving the visibility, whilst also saving energy. It reduces the power consumption while keeping the visibility as optimal as possible, making it a great choice in automotive applications.

Working Principle

The working principle of NCV786XXAR20GEVK module is simple and understandable. It makes use of dual 16-bit PWM controllers and a dimming current adjuster to precisely manage the LED brightness based on the user’s requirements. The PWM controllers are mainly used to adjust the LED brightness while the dimming current adjuster helps to maintain a consistent brightness level between the LEDs, even when the user is adjusting the current intensity.In addition, the NCV786XXAR20GEVK module also offers a number of protection features to prevent damage to the LEDs. It includes thermal protection, under-voltage lockout and brown out reset protection. It also offers a three-way enable pin to allow the users to turn the module on, off or enable them in power down mode to further reduce system power consumption.In summary, NCV786XXAR20GEVK is a great LED driver module for LED applications, thanks to its advantages like flexibility, dimming functionality and energy savings. It provides the added functionality of PWM control and dimming current adjuster, and a number of protection features to keep the connected LEDs safe. Thus, making it a great choice for various LED applications.
