The EA6906UCADJ evaluation board is an off-line power supply reference design board that features a variety of adjustable switching power converters from a range of values of 3.3V, 5V, 12V and 24V. It uses the patented analog current-mode control technique to provide an efficient and stable power supply for a variety of applications. The board is also capable of input voltage ranges from 10 V-130 VDC. It is designed to provide reliable and robust power supplies to meet the needs of a wide range of applications such as LED lighting, charge controllers, and sensor applications.

The board is powered by a high-efficiency controller, the UCC28600D, and is provided with appropriate drivers, input terminals, and output terminals to make the PCBs quickly available for prototyping and evaluation. It also features proprietary thermal protection circuitry to protect the device from overheating. The board is prepared to enable the user to evaluate all the main functionalities of the device. It is very easy to get started with the EA6906UCADJ evaluation board with its user friendly graphical user interface (GUI). It is designed to provide testing and evaluation of a full range of power supply features including step-down, synchronous buck, step-up, and Active Clamp Forward (ACF) topologies.

The working principle of the EA6906UCADJ board is based on the UCC28600D synchronous buck controller. This device supports an analog current-mode control architecture for cost-efficient and high-performance power converters. The current sensing circuit drives the power switch resulting in a linear current path and improved efficiency. This could achieve up to 90% efficiency in a 3.3V power supply operating in the low current range and up to 95% in the high current range. Furthermore, the synchronous buck topology reduces the AC ripple component and reduces EMI by providing a well-filtered constant output voltage.

The board is easy to use and provides a good platform to evaluate various features and parameters of the device. The UCC28600D embedded system is designed to provide multiple protection functions, including overvoltage protection, current-limit protection, input overvoltage protection, output short circuit protection, and thermal protection. In addition, it also has a switch-mode regulator line regulation to maintain a good output voltage for smooth transition across the input voltage.

The EA6906UCADJ evaluation board is an ideal choice for LED lighting, charge controllers, and sensor applications due to its efficient power conversion and adjustable switching power converters. It is designed to provide reliable and robust power supplies to meet the needs of varied applications. With its user friendly graphical user interface, it is very easy to get started with the board and to evaluate its various features and parameters.
