The NCV786XXAR10GEVK is a high performance and low cost monolithic device from ON Semiconductor that offers interleaved current and temperature regulation for high-power LED engines. This device integrates a 250mA Constant-Current LED Driver and a Buck-Boost or Buck-Boost + Buck Regulator. It also has an integrated under-voltage and over-voltage monitoring feature that controls the LED dimming current according to the LED voltage. In addition, the NCV786XXAR10GEVK includes several programmable features to simplify the development of LED engines.

The NCV786XXAR10GEVK is best suitable for automotive lighting, industrial lighting, and backlighting applications. It is an ideal device for applications requiring precise regulation of LED strings while protecting against over-current and over-voltage conditions. It features a wide adjustment range of LED current, allowing designers to optimize the design to meet specific demands.

The NCV786XXAR10GEVK evaluation board incorporates a LED driver device to illustrate the LED driver functionality. The board includes a DC-to-DC converter with a two-stage topology for controlling a pair of LED strings. The main feature of the device is that it can adjust the LED current level with temperature compensation allowing the LED driver to maintain a constant current even with temperature variation of the LED junction. In addition, the voltage regulation feature ensures that the LED current does not exceed the safe operating limits."

The NCV786XXAR10GEVK evaluation board operates using a standard 14V source. By adjusting the external enable input the board switches between the two channels. When the enable pin is set to a high voltage the board switches between the two channels and when the enable input is set to low the board is set to the low power mode. The evaluation board also includes adjustable current settings and output voltage settings to allow for easy customization. An over-temperature protection feature is also included in the evaluation board to ensure safe operation of the device. The NCV786XXAR10GEVK evaluation board also includes an on-board temperature sensor to monitor the temperature of the device. This feature helps to ensure the device is operating safely within the specified temperature range.
