Evaluation and Demonstration Boards and Kits are popular tools available for designing, testing and troubleshooting electronic devices in a variety of industries. STEVAL-ILB001V2 is one evaluation board that can provide application fields and working principles for the interested user.

This evaluation board is a comprehensive, low-power LED light engine evaluation plate. It has a wide range of applications including automotive lighting, residential lighting, and general lighting. The STEVAL-ILB001V2 has a high-power LED driver, which includes a constant current source and a voltage step-up DC/DC stage. It also includes a user friendly programming interface that allows the user to configure and operate the board. Users can modify the various lighting parameters such as the power setting of available LED driver channels, color temperature and display impact.

In addition to user friendly programming the STEVAL-ILB001V2 provides users with a number of protection features such as current limiter, thermal protection, over voltage protection and anti-EMI protection. This ensures reliability and safety of the light engine and protects the board from external interference.

The STEVAL-ILB001V2 also includes a master control unit (MCU) which enables the user to control the LED engine from a PC, laptop or any other compatible device.The MCU also offers the user the ability to schedule and test LED light engine parameters. This ensures the LED engine will reach the desired level of lighting performance.

In terms of its working principle, the STEVAL-ILB001V2 takes a DC voltage power supply as an input. This input is converted into a constant current and fed to the power stage of the LED driver. The power stage consists of a buck converter followed by a N- Channel MOSFET, the function of which is to generate multiple channels of constant current for driving up to three strings of LEDs.

The voltage step-up DC/DC stage provides the LED driver with a driving voltage up to 36V. The MCU takes control of the LED illumination and the user can modify the lighting parameters using the user friendly interface. The board also provides the user with protection features such as over voltage and thermal protection.

The STEVAL-ILB001V2 evaluation board provides users with a comprehensive solution for designing and testing LED light engines. It offers wide range of applications ranging from automotive to general lighting and provides users with features such as user friendly programming, current limiter and thermal protection. This ensures reliability and safety of the LED light engine. Its working principle is simple and straightforward, taking a DC voltage as an input and converting it into a constant current, which is fed to the power stage. The board also has a voltage step-up converter that is used to provide a driving voltage for the LED driver.
