The STEVAL-ILL016V2 is a fully integrated, flexible and low cost LED driver evaluation board designed by STMicroelectronics. It offers a simple solution to power and control a wide range of AC, DC or hybrid and fluorescent LED lighting applications. This board integrates dual-channel high efficiency synchronous rectified buck converters, and a wide array of features such as current and voltage regulation, over voltage protection, dimming capability and thermal protection.

This driver evaluation board has two different application fields. Firstly, it is used for inductive lighting applications, such as street lighting and industrial lighting. The board features adjustable feed-forward compensation and allows to optimize the behaviour at start up. This makes the STEVAL-ILL016V2 a very suitable solution for applications which require high system efficiency and a wide dimming range.

The STEVAL-ILL016V2 also enables an easy integration of capacitive lighting loads into the driver circuit. This is due to the wide operation range of the buck converters, a feature that makes the board suitably suitable for applications such as down lights and ceiling lights.

In terms of design and operation, the STEVAL-ILL016V2 follows a simple and effective approach to LED driver control, allowing designers to quickly and easily integrate a reliable LED driver into their designs. The user has total control over the operating parameters of the device, such as the output current, voltage, frequency and the dimming ratio of the LED. The user can also make use of the integrated pulse-width modulation capability to generate desired dimming effects.

The STEVAL-ILL016V2 also features three different types of external control interfaces, which can be used to control the driver. These include a digital TTL signal, an analog signal or remote control by an external signal. This helps the user to integrate the STEVAL-ILL016V2 into an existing system with a minimum of effort.

When it comes to working principle, the STEVAL-ILL016V2 uses synchronous buck converters for extremely high efficiency and low component losses. The two outputs can be individually set and regulated by integrating two control loops. The power section of the board integrates transistors, inductors and capacitors, along with resistive and capacitive elements to create the optimal solution for LED lighting applications. Furthermore, the board offers current regulation, voltage regulation, over voltage protection, thermal protection and dimming capability.

The STEVAL-ILL016V2 is an ideal solution for LED driver applications, providing a low cost and flexible solution for a wide range of inductive and/or capacitive lighting applications. It offers an efficient, easy to use and powerful solution for controlling LED lighting applications.
