The XRP7618EVB is an evaluation board from Dialog Semiconductor that is designed to test the feasibility of LED driver designs in various projects. The board provides a versatile platform to evaluate various LED drive options, allowing users to quickly evaluate and experiment with different LED driver design configurations. The evaluation board also use Dialog\'s XRP7618 integrated LED driver IC which has been designed to increase efficiency and reduce system cost.

The XRP7618 EVB is a four-channel LED driver board with programmable current sensing, customizable dimming, and four channels of pulse width modulation (PWM) or constant brightness (CC). The board supports 2.5 A/channel of load current and spreads the output voltage over four channels, making it a great choice for multi-LED applications. The board also features four channels of low-side N-channel MOSFETs and four channels of medium-side P-channel MOSFETs, allowing users to control each channel independently.

The XRP7618 EVB comes equipped with an embedded real-time clock for dimming control, as well as a built-in temperature sensor for power-saving thermal management. The board also comes with an optional software module, allowing users to configure the board settings from a PC. The board has a wide input range from 1.7 to 5.5V, and offers two control modes: synchronous and asynchronous. The underlying driving deep-dim control further enhances its energy efficiency.

The key feature of the XRP7618 EVB is its constant-current system, which ensures that the load current is always kept equal to the reference current. This ensures that the output load always maintains a constant brightness, thereby improving the system reliability and overall performance. The board also features adjustable overvoltage protection, which keeps the voltage across each channel within a safe operating range. Furthermore, the adjustable overcurrent shutdown feature prevents the system from becoming damaged due to over-current.

The XRP7618 EVB is a versatile LED driver solution that makes it easy to develop and evaluate LED driver designs. It provides features like current sensing and adjustable dimming, making it an ideal choice for LED applications that require multiple channels of dimming and brightness control. Its wide input range and adjustable overload protection offer reliable and stable performance. Furthermore, its embedded real-time clock and temperature sensor make it easy to integrate with external controllers and other devices for optimal thermal management.
