It is also designed with industry-leading features such as 3A load drive capacity, 3.9MHz constant switching frequency, active input current control, and input voltage operating range suitable for USB PD source environment.

The TPS2546EVM-064 is designed to work in an application field where power distribution between multiple devices is needed. It supports the USB PD protocol to help designers create products for this application. It is suitable to be used in a variety of products, ranging from mobile devices, automotive, medical equipment, and home/industrial equipment. The EVM helps developers quickly and easily test the performance of the TPS2546 within their product designs and allows the developers to produce prototypes quickly.

In terms of working principle, the TPS2546EVM-064 features a synchronous buck controller which helps the product achieve highly efficient power conversion. It uses pulse width modulation (PWM) to control the output voltage and current of a DC-DC converter. The frequency of the PWM signal can be adjusted with the help of an external resistor, allowing the user to optimize the power efficiency. The input voltage is also regulated with the help of active current control, enabling the product to achieve a high input voltage operating range.

The TPS2546EVM-064 also supports the USB PD protocol. It acts as a power source to other devices by providing power supply over the USB PD cable. The power supply can be automatically managed by the controller, reducing the design time needed for engineers to create solutions. In addition, the product comes with a power LED signal which alerts the user when the device is enabled and supplying power. This feature can be used as a visual indication to the user of the product’s power status.

In conclusion, the TPS2546EVM-064 is an efficient power module designed to evaluate the performance of the TPS2546 USB PD controller. It is suitable for application where power distribution between multiple devices is needed. The EVM also helps designers to optimize power efficiency with features such as active current control and adjustable PWM frequency. The EVM also has the capability to act as a power source over the USB PD protocol. With all of these features, the TPS2546EVM-064 is an ideal solution for engineers who need to quickly design a product with minimal effort.
