STEVAL-ILL001V1, categorized as Evaluation Boards - LED Drivers, is an advanced and efficient LED driver with a 120-W output. It is suitable for applications like indoor and outdoor lighting, wall or floor mountings, down lights, street lights and spot lights. This driver uses two efficient topology configurations - dual-stage buck or buck-Boost or buck-Boost/PNP - depending on the system requirements, and can handle up to two LED strings with multiple parameters like voltage, temperature and current, plus it can control all input power components (MOSFETs and Schottky diodes).

STEVAL-ILL001V1 works by using its integrated switching regulators and VLSI controllers. It has two isolated LED driver channels – one for constant current applications and the other for non-constant current applications. These channels can be used for led driving without any additional device, allowing for a maximum accuracy of the output current to match with any LED module characteristics. Moreover, it also includes an on-board conversion for AC/DC, so that the driver can be powered either from a mains AC or a DC source.

The STEVAL-ILL001V1 evaluation board features a built-in LED driver and onboard LED current sensing, along with an isolated DC-DC converter that allows the user to control the LED current levels precisely. With a maximum output of 100 W and up to two LED strings, this LED driver is suitable for both indoor and outdoor lighting applications such as streetlights, wall or floor mountings, and down lights.

The STEVAL-ILL001V1 works by implementing two effective topology configurations – dual-stage buck and buck-boost/PNP – depending on the system requirements, which enables the user to obtain adjustable output current with high efficiency and accuracy. The integrated current sensing circuit allows primary current setting, and provides the output current the necessary feedback from the switching regulators in order to keep an accurate and stable output current.

The STEVAL-ILL001V1 also includes various protection features, such as UVLO, OVP, SCP, OCP, OTP, and thermal shutdown, and it comes with an innovative thermal design that reduces the operating temperature of the switch regulators, allowing a high power density and a reduced conductor size in the application.

In conclusion, the STEVAL-ILL001V1 is an efficient and reliable evaluation board that takes on the challenging task of providing an accurate and stable output current in a variety of applications. Its easy-to-use features, integrated circuit protection and topology configurations make this evaluation board the ideal solution for designers looking for an effective LED driver.
