Working Principle
The TPS92512EVM-001 is designed to provide a single LED drive output at 24V and up to 5A. The board features an on-board step-down converter, an integrated PWM controller, an on-board regulator and an over-current protection circuit. The board supports two output channels, with each channel capable of driving up to 2A of current at 5V. It features adjustable current regulation for each channel for accurate brightness control. It is also equipped with a temperature compensation function which helps ensure accurate output current regulation across temperature fluctuations.The board includes two separate input power supplies: a 5V input and a 24V input. The 5V is used to power the step-down regulator, while the 24V is used to power the LED driver. The two power supplies are connected together with an isolating transformer to avoid interference. The LED current is regulated by the integrated PWM controller, which is used to generate a signal that can control the LED current and brightness.The board also includes a 3.2V LDO (low-dropout regulator), which can be used to power an external voltage regulator circuit. The LDO provides a stable power supply for the microcontroller and is capable of providing up to 5A of current. It has a wide voltage range, making it ideal for applications where the supply voltage may vary from 5V to 24V.The board also features spread-spectrum technology, which helps reduce electromagnetic interference. Spread-spectrum allows the LED driver to reduce the amplitude of the output voltage and frequency of the LED current pulses. This helps reduce any interference that may be caused by electromagnetic radiation from the LED current pulses. The spread-spectrum output makes the board more suitable for applications such as LED lighting, where EMI is a concern.Conclusion
The TPS92512EVM-001 evaluation board is a reliable and cost-effective platform for evaluating the performance of the TPS92512 LED Driver. It supports up to two independent channels, allowing two LED drivers to be connected at the same time. The board also features programmable LED status, spread-spectrum operation, current sink temperature compensation and low power consumption. It is an ideal solution for LED lighting applications requiring dimming or flicker-free operation. With its feature set and low cost, the TPS92512EVM-001 evaluation board makes it easy for developers to quickly evaluate and prototype LED driver solutions for a wide range of motion-oriented applications.
