TPS63027YFFR DC DC Switching Regulators

The TPS63027YFFR is an efficient, small Low Qg,fully integrated DC/DC synchronous step-down converter with integrated logic compatible enable from Texas Instruments. This IC is ideal for applications such as 5V, 12V, and 24V low power High-density Telecom power supplies, Point of Loads, or any other applications requiring low output voltage with minimal external components. The TPS63027YFFR operates from 3V to 18V input voltage, and the current output is adjustable from 0.3A to 5.5A.

Application Field

The TPS63027YFFR is an efficient low power DC/DC synchronous buck converter, suitable for a wide range of applications. It is well-suited for 5V, 12V, and 24V applications in consumer electronics and telecommunications due to its high efficiency and small size. It can also be used in battery-powered applications such as portable medical equipment and mobile gaming systems. Its adjustable output current of 0.3A to 5.5A make it ideal for Point of Load applications where the current needs to be adjusted to meet the device’s power requirements.

Working Principle

The TPS63027YFFR uses a synchronous buck topology that allows for a high efficiency output voltage. Most DC/DC converters use two or more power switches to toggle the power stage on and off. This results in a high switching loss and a lower efficiency. The TPS63027YFFR, however, uses a single switch to control the output. A controller uses a fixed frequency to control the switch, allowing for the higher efficiency. This eliminates the need for an inductor and allows for a smaller package size. The device also features an internal PWM or PFM output that can be used to reduce ripple and improve the efficiency of the converter. The PWM mode is used when the load requires a high output current, while the PFM mode is used when the load requires a lower current. The PWM/PFM switch-over point can be adjusted via an external resistor. The TPS63027YFFR also features integrated protection and control logic, allowing for a more reliable operation. The protection includes an overvoltage protection (OVP) circuit, a reverse current protection (RCP) circuit, and a thermal shutdown (TSD) circuit. The integrated control logic also helps to improve efficiency and reduce the need for external components.

Conclusion

The TPS63027YFFR is an efficient, low-Qg, fully integrated DC/DC synchronous step-down converter from Texas Instruments. Its wide range of applications make it suitable for a variety of consumer electronics and telecommunications systems. The high efficiency of the converter is a result of its synchronous buck topology and integrated PWM/PFM output. Additionally, its integrated protection and control logic help to ensure reliable operation.
