DC DC converters are widely used in many different applications, ranging from industrial and automotive to telecommunications and consumer electronics. The TPS84259RKGT is an integrated buck DC DC converter designed especially for low-power applications, offering high efficiency, low-noise operation, small size, and ease of use. Here, we will discuss its application field, working principle, and other features.

Application Field

The TPS84259RKGT can be used for many different applications. It is an ideal solution for embedded and consumer applications such as cell phones, PDAs, LCD/LED TVs, notebook PCs, and tablets. It is also suitable for automotive applications, such as automotive infotainment systems, car computer systems, and automotive power systems.

Working Principle

The TPS84259RKGT is an integrated buck DC DC converter. It works by synchronously switching between two operational states: buck and boost. In the buck state, the converter operates as a step-down converter, reducing the input voltage and delivering the output at a lower voltage. In the boost state, the converter operates as a step-up converter, increasing the input voltage while delivering the output at a higher voltage. The switching between the buck and boost states allows the TPS84259RKGT to convert a voltage from one range to another, and is the secret behind its high efficiency.

Other Features

The TPS84259RKGT features high efficiency, low noise operation, and a small footprint. It has a fast transient response time of 0.2µs, and can operate at a duty cycle of up to 98%. It also has a power-saving mode that allows the converter to enter a low-power standby mode when no load is present. For convenience, it comes in a flip-chip package and can be easily mounted onto a printed circuit board.

Conclusion

The TPS84259RKGT is an integrated buck DC DC converter designed especially for low-power applications. It has various features that make it perfectly suited for embedded and consumer applications, as well as automotive applications. Its high efficiency, low-noise operation, small size, and fast transient response time make it a great choice for applications where power, size, and performance are critical.
