Introduction

EA6357NH evaluation board is a multi-functional LED driver, integrating AC/DC, DC/DC, PFC, and high frequency boost, buck, SEPIC, flyback and Cuk topologies, and that meets the requirements of high power LED lighting systems. The board can also be used to rapidly evaluate and validate the application of DC/DC controller ICs up to 30W.This evaluation board is mounted on a PC104 style frame and provides bridges and SMT test points for connection to LED power supply components. These test points offer a convenient way to measure characteristics such as the LED current ripple and input current profile.

Application Field

EA6357NH has been designed to rapidly evaluate and validate the application of DC/DC controller ICs. It offers the flexibility of controlling DC/DC converters up to 30W, as well as integrating multiple DC/DC converters into one power supply system. The board can be used in various applications such as LED illumination, automotive lighting, communications, and industrial applications. In LED illumination applications, EA6357NH is suitable for LED strips, arrays, and light bars. This evaluation board can also be used in automotive lighting applications such as vehicle accessory lighting, interior lighting, and exterior lighting. Moreover, the board is applicable for the power supply in telecommunications, computer, and consumer electronic products.

Working Principle

The working principle of the EA6357NH evaluation board can be divided into two components: the AC/DC converter and the DC/DC converter.The AC/DC converter works with a mains voltage input, firstly rectifying the AC voltage from the mains to a DC voltage source. This then serves as an input voltage for the buck-boost converter. The buck-boost converter is responsible for the voltage transformation in order to adjust the output voltage level which is then used for lighting load supplied by the LEDs.The DC/DC converter is responsible for energizing the LEDs. The DC/DC converter works with a DC input voltage and regulates the output voltage to an adequate level for the LEDs. It can either be a buck or boost converter, depending on the chosen voltage level at the input. In addition, the EA6357NH can be used for various other DC/DC topologies, such as flyback, Cuk, and Sepic.

Conclusion

In conclusion, EA6357NH evaluation board offers a versatile platform for evaluating and validating DC/DC controller IC applications. It offers a simple and quick way to develop LED lighting systems, supplying LEDs with power up to 30W. The evaluation board is capable of using multiple topologies in one system, including AC/DC and DC/DC conversion. It is also suitable for various applications such as LED illumination, automotive lighting, communications, and consumer electronic products.
