The NCV7683GEVB ((Evaluation Boards - LED Drivers)) is a robust and cost-effective LED driver solutions. It is designed to help system integrators and engineers to evaluate the features and performance of the NCV7683, an integrated high-brightness LED (HB LED) driver for enterprise-class lighting applications. This evaluation board is designed for use with an external 400mA constant current source and an external power supply, providing an adjustable output current up to 450mA through different configurations.

The board consists of the NCV7683 controller IC, a pair of small high voltage Mosfets and a 10Ω/2W floating current sense resistor. The controller IC includes essential components such as a corrected LT1763 linear voltage regulator, a CSD10508 P-FET switch, an ESD clamp and two integrated low side drivers. The IC also features two functions called (ScanLight) and (NightLight), which are designed to increase the efficiency of lighting applications.

In addition to its low cost, the board also features low operating temperature and low component count. The board also supports various pulse-width modulation (PWM) frequencies from 150Hz to 6kHz, suitable for applications that require constant current as well as dynamic current modes. Comprehensive protection features are integrated into the board including over-temperature, over-voltage and under-voltage protection, while a minimum of noise is generated due to the integrated PFC circuit.

In its basic configuration, the board is capable of outputting up to 450mA of constant current with a minimum turn-on voltage of 9V and a maximum turn-on voltage of 15V. Its efficiency is rated at up to 90%, while the operating temperature range is 0°C to 70°C. The board also supports a wide range of LED operating voltages and is compatible with 1-5 series-connected LEDs, which can enable various lighting applications, such as spotlights, downlights, decorative lighting and more.

The board also takes advantage of the (ScanLight) and (NightLight) features, which work by automatically reducing the output of LEDs when not actively used. Both features are designed to reduce the power consumption of the associated application and also extend the life of the LEDs. This can help to extend the lifecycle of the board and associated lighting application, as well as lower the operating temperature of the board, thus increasing its efficiency and reliability.

For those who are looking for a robust, cost-effective and efficient LED driver solution, the NCV7683GEVB is a great choice. With its integrated PFC circuit, (ScanLight) and (NightLight) features, and its compatibility with 1-5 series-connected LEDs, it is an ideal solution for enterprise-class lighting applications.
