EL7630IWTZ-EVAL Evaluation Boards - LED Drivers

The EL7630IWTZ-EVAL is an evaluation board for LED drivers, featuring the EL7630IW-TZ constant current LED driver. It is designed to help users quickly evaluate and test the EL7630IW-TZ LED driver. The board is a cost-effective and efficient tool for driving a 12V LED string with a constant current of 2A. The board only needs a standard DC 24V power input and no additional components are required.

The EL7630IWTZ-EVAL board\'s evaluation purpose is to allow users to study and measure LED string power and LED current in a real-time environment. The board provides adjustable output current which can be set by simply turning the two common screws located in the power supply area. The output current can be set with resolutions of 0.075A up to a maximum of 2A.

The board supports four different LED driving solution modes. These include constant current, linear current, PWM current and constant voltage. The output current can be adjusted via external voltage control, allowing for programmable adjustments over a range of 0V to 500mV. The linear current mode provides an adjustable output current profile that follows the supplied input voltage, whilst the PWM current mode offers programme PWM signal with output current following the signal level.

The EL7630IWTZ-EVAL board is also equipped with a temperature compensation feature which allows the regulator\'s output current to be adjusted directly in accordance with the output LED current at varying temperatures. This ensures that the output current is kept within a fixed range whatever the environmental conditions are.

The board is fitted with an over-temperature protection circuit. This is designed to shut down the output in case of any over-temperature conditions, resulting in an extended life-time of the system components.

The EL7630IWTZ-EVAL board has been designed with a built-in user interface. This consists of two status LED’s which indicate the presence of power, and an analogue voltage control interface. In addition, the board is equipped with a small LCD panel, which can display all the required parameters like output current and voltage.

In conclusion, the EL7630IWTZ-EVAL is an effective and efficient solution for driving LEDs with a constant current. Its adjustable output feature and temperature compensation capabilities make it ideally suited for applications featuring LED strings with a 12V power input. Furthermore, its user interface provides an easy and intuitive way to control and monitor the board\'s parameters.
