TPS3890EVM-775

Evaluation and Demonstration Boards and Kits are PCBs and kits particularly designed for evaluation and application development purposes. Among them, the TPS3890EVM-775 evaluation module (EVM) for the TPS3890 device is an example. The TPS3890EVM-775 is an evaluation and demonstration board designed especially for the commercial use of the TPS3890 device. The system, featuring an 8-pin limited device voltage supply (LDVS) regulator in a small 2mm x 2mm QFN package, provides an adjustable output current of up to 12A with low standby current of 500nA. It offers an ideal solution for LDVS applications involving low-standby power consumption, low dropout voltage and full load current.The system can be used to demonstrate the functionality of the TPS3890 device as well as providing a solution to common LDVS applications. It can be used in a variety of applications, such as battery powered systems, automotive electrical systems, consumer electronics, industrial electronics and other similar products.The TPS3890EVM-775 board is designed with the TPS3890 device integrated on it and several other components to leverage the full potential of the device. The system has a jumper enable and disable switch to control the output current of the device. Additionally, the board has an adjustable load resistor, an LT3054 low-input-voltage regulator, a 3.3 V LDO, and a voltage supervisor IC.The working principle of the system is very simple. The voltage supervisor IC is used to monitor the input voltage, while the LDO provides the main power for the device. When the voltage supervisor detects an appropriate input voltage, the LDO powers up and the device starts on-time. When the user applies a load to the device, the TPS3890 device senses the current and regulates the output voltage according to the load. The TPS3890 chip also has a feature of programmable over temperature protection, making it suitable for a variety of applications.Due to its efficient and reliable performance, along with its high power density, the TPS3890EVM-775 board is a great solution for a variety of applications. It is a perfect demonstration board for designers who want to evaluate the device for commercial use and yet benefit from its full functionality.
