Introduction

Power management integrated circuit (PMIC) is an integrated circuit that provides an efficient way of managing the power distribution, load drivers, and other features of a system. One such PMIC is the TPS65280RGER from Texas Instruments. This device combines a range of features that make it suitable for a variety of applications. In this article, we will look at the application field and working principle of the TPS65280RGER.

Application Field

The TPS65280RGER is suitable for applications in a variety of markets. This includes enterprise and industrial market segments, including server and storage systems, devices such as medical imaging, and industrial chargers. This device also finds applications in devices such as digital cameras and mobile phones, where it is used as a power management solution.In addition to providing power management solutions, the TPS65280RGER can act as a complex regulator in a variety of systems. This is particularly beneficial in systems that are complex, requiring multiple power rails to be managed and controlled efficiently.

Features

The TPS65280RGER provides a range of features that are suitable for various applications. These features include:• A 2.5V to 5.5V input voltage range• A wide variety of output voltage options• FET switching for accurate load switching and current sensing• Programmable fault and overvoltage protection• Programmable soft-start and overvoltage protection• Output current limiting• Enable review and disable via an external pin

Working Principle

The TPS65280RGER is comprised of a controller IC and an external switch. The controller IC works in combination with an external switch to provide the power rails and other power management features.The controller has two primary tasks – controlling the voltage on the power rails and monitoring the output. The controller is responsible for regulating the output voltage of the rails and protecting the system from overvoltage or fault conditions. The controller also monitors the output and can switch off the output when the voltage exceeds a certain level or when the temperature becomes too high.The controller is programmed to set the output voltage based on the input voltage that is supplied. It will then monitor the output and respond to fluctuations in the input voltage. The external switch is used to enable and disable the output. It is also used to provide current sensing and load switching.

Conclusion

The TPS65280RGER from Texas Instruments is a powerful and versatile PMIC that provides a comprehensive power management solution for a variety of applications. This device combines features such as a wide input voltage range, a variety of output voltage options, FET switching, and programmable fault and overvoltage protection to provide an efficient and reliable power supply. This device can also act as a complex regulator to manage multiple power rails in complex systems.
