Introduction

The UCC25710EVM-654 evaluation board (EVM) provides an ideal platform for the evaluation and design of high performance LED drivers using Texas Instruments UCC25710 device. The UCC25710 is a current-mode LED driver which can directly drive up to 10 LED strings with a maximum LED drive current of 3 Amps. The EVM includes a switching power source which can output 0-24V to the LED drivers and there is also an adjustable current controller, temperature sensors and a USB interface for configuration and data logging. This article will focus on the application field and working principle of the UCC25710EVM-654.

Applications

The UCC25710EVM-654 is most suitable for applications which need high performance LED drivers and/or adjustable current controllers. The EVM is capable of driving up to 10 LED strings and also features adjustable current controllers which can be used to adjust the output current of each string. This makes it ideal for applications such as industrial and commercial lighting, automotive lighting and any other application which requires high performance LED drivers.

Working Principle

The UCC25710EVM-654 is based on the Texas Instruments UCC25710 device which is a high-performance constant current switch-mode LED driver. The EVM contains an adjustable current controller, temperature sensors and a USB interface for configuration and data logging. The UCC25710 device takes in a DC voltage and converts it into a current-mode control signal. This signal then drives up to 10 LED strings with a maximum LED drive current of 3 Amps. The current controller is adjustable and can be used to adjust the output current of each string. The temperature sensors are used to measure the temperature of the LEDs, thereby allowing the driver to make adjustments as needed.

Conclusion

In conclusion, the UCC25710EVM-654 is an ideal evaluation platform for the design and evaluation of high performance LED drivers. It can drive up to 10 LED strings with a maximum LED drive current of 3 Amps and includes adjustable current controllers, temperature sensors and a USB interface for configuration and data logging. The EVM is suitable for applications such as industrial and commercial lighting, automotive lighting and any other application which requires high performance LED drivers.
