The STEVAL-LLL001V1 is a high-power LED driver evaluation board based on the STHV5950 high voltage and non-dimming LED controller IC. This board is suitable for a wide range of LED applications from indoor and outdoor lighting to automotive and display applications. It is used for driving up to eight LED strings in series at a wide range of output voltages, and is designed to achieve wide range dimming. It features several protection mechanisms including over-temperature and over-current protection.

The STEVAL-LLL001V1 has two power inputs, a line voltage input and a bus voltage input, with a maximum voltage of 35V and a maximum current of 1A. It has an output voltage range of 0-60V, and a maximum output current of 5A. It also includes a compensation network that allows for output voltage accuracy over temperature and load changes. The LED driver evaluation board has two control inputs, one for dimming and one for current regulation.

The STEVAL-LLL001V1 is designed to be easy to use. It has two potentiometers, one for dimming control and one for current regulation, as well as an on-board LCD display that provides a visual representation of the output voltage, current, and dimming level. The board also includes a PCB that allows the user to customize the application such as adding a relay or using a different control voltage.

The STEVAL-LLL001V1 is designed for driving eight LED strings in series. The output voltage depends on the number of LEDs in each string and can range up to 60V. The maximum output current is 15A. The board also features an adjustable current regulator, allowing the user to configure the proper operating current of the LED array. It also features an integrated compensation network for better regulation of the output voltage and for over-temperature/over-current protection.
