Introduction To TPS62674YFDR

The TPS62674YFDR is a synchronous buck converter, operating in a 4.5V to 28V input voltage range. Its synchronous step down switch enables high efficiency and superior thermal management. It has a low quiescent current of just 62µA (Operating Mode), and the on-board MOSFET and inductor eliminate the need for external components. The TPS62674YFDR can deliver up to 6A of output current and its output voltage is adjustable from 0.91V to 5.25V.

Furthermore, its tiny 3mm x 3mm footprint makes this product ideal for space-constrained applications such as mobile phone chargers, USB wall adaptors and other wearable products. The TPS62674YFDR also offers a wide range of protection features, including cycle-by-cycle current limit, thermal shutdown and UVLO.

Application Fields

The TPS62674YFDR is mainly used in mobile device applications with high current, space-constrained requirements. Examples include USB wall adaptors, cloud computing servers and storage systems, automobiles, consumer electronics, gaming peripherals and medical devices. Its flexible voltage and current ratings, coupled with its low quiescent current and industry-leading space-saving capabilities make this product suitable for a wide range of DC–DC applications.

Working Principle

As a state-of-the-art synchronous switching regulator, the TPS62674YFDR is able to deliver higher peak currents and better efficiency than traditional linear regulators. The synchronous buck converter uses an output transistor in combination with an inductor to convert a fixed input voltage into an adjustable output voltage, and transfer power between two circuits.

This process is achieved by switching the output transistor between two states (on and off) at a high frequency, thus regulating the amount of current that passes through the inductor and regulating the output voltage. This technique is much more efficient than a linear regulator and results in reduced output ripple and higher efficiency.

The TPS62674YFDR is equipped with an on-board MOSFET and inductor, thus eliminating the need for external components. Additionally, the TPS62674YFDR features adjustable output voltage and programmable switching frequency, allowing users to optimize their power solutions to meet their application requirements.

Conclusion

The TPS62674YFDR is a synchronous buck converter, ideal for applications requiring high current, efficient power management and space constraints. It delivers up to 6A of output current and its output voltage is adjustable from 0.91V to 5.25V. It has a low quiescent current of just 62µA (Operating Mode) and comes equipped with an on-board MOSFET and inductor, eliminating the need for external components. Additionally, it offers a wide range of protection features, including cycle-by-cycle current limit, thermal shutdown and UVLO.

The TPS62674YFDR is a valuable solution in providing reliable and efficient power for a variety of mobile device applications, such as USB wall adaptors, automobiles, consumer electronics, gaming peripherals, medical devices and more.
