The STEVAL-TLL004V1 is an LED Driver module for evaluation boards and is designed to serve as a professional tool for laboratory use. It is used to simulate lighting scenarios and to explore the field of LED lighting applications. The STEVAL-TLL004V1 is designed to be used in “mains-connected” LED lighting applications and is compliant with the Smart Lighting Protocol. The STEVAL-TLL004V1 contains several features to meet the requirements of professional lighting applications, including mains-connected dimming, stand-by power reduction and emergency lighting.

The STEVAL-TLL004V1 module contains both a high-voltage and a low-voltage version. The high-voltage version has two power outputs capable of driving two sets of LEDs independently or in parallel. The low-voltage version contains one output and is mainly used in small area lighting applications.

Besides offering the flexibility to configure the settings of the outputs, the module also offers an angled heatsink design that provides superior performance, as well as an integrated filter design to eliminate noise and interference. The board also offers several LED drivers integrated into the system and a digital dimming interface. Furthermore, the module also offers an LED support box and emitter to further customize the lighting application.

As for the working principle of the STEVAL-TLL004V1, it is based on the smart lighting protocol (SLP). SLP is a backend control and communication protocol which enables direct control of connected LEDs in standalone, point-to-point, and networked lighting systems. SLP provides an open standard for communication between connected LED systems and enables the integration of LED lights with various control systems, such as 0–10V dimmers, occupancy sensors, light sensors, etc. Through this protocol, LED lighting solutions can be adapted to different requirements and settings while ensuring a proper operation.

Furthermore, the STEVAL-TLL004V1 also offers digital dimming control. This is done through the use of a digital dimming interface. The interface works by providing a digital signal that is fed into the LED system via the digital dimming pin. The digital signal is then used to adjust the brightness level of the LEDs by changing the current flow in the system. Additionally, the STEVAL-TLL004V1 also offers other features, such as temperature sensing and monitoring, and A/C voltage detection and reporting.

All in all, the STEVAL-TLL004V1 is an evaluation board for LED drivers used in the field of LED lighting applications. It offers several features that can be configured in order to meet the requirements of professional lighting solutions. It also offers a smart lighting protocol for direct control of connected LEDs, as well as a digital dimming interface for adjustable brightness levels of LED systems. These features combined make it a reliable and robust LED driver evaluation board for various LED lighting applications.
