TPS54040DGQR application field and working principle
The TPS54040DGQR is a high-performance synchronous buck converters and is part of Texas Instruments\' performance SIMPLE SWITCHER® family. Specifically designed for high-current applications, the TPS54040DGQR is ideal for storing and distributing low-voltage point-of-load (POL) power while providing high efficiency over a wide input voltage range.The TPS54040DGQR is classified under PMIC – Voltage Regulators – DC DC Switching Regulators and its application field includes, but is not limited to, telecom and networking, industrial, computing and storage, set-top box and consumer electronics. This buck regulator offers dual output along with adjustable and fixed-output solutions to accommodate designs that require high-current capability.From its application field to working principle, this article offers an overview of the TPS54040DGQR high-performance synchronous buck converters.How Does the TPS54040DGQR Work?
The TPS54040DGQR buck converter synchronizes transfers of energy from the input to the output stage with the switching frequency, allowing it to regulate an output voltage. It achieves this by switching pulses of the current through a inductor or power transformer, which will store and redistribute that energy to the output voltage by using an internal high-frequency clock to dictate its timing.The TPS54040DGQR utilizes the synchronous rectification technique technique to reduce the power losses due to switching and to increase the efficiency of the power conversion process. As current is required to flow from the inductor to the load, it flows through either N-channel or P-channel power MOSFETs. As the two MOSFETs are switched at the same time one is conducting and the other is blocking, offering high efficiency operation.The TPS54040DGQR also features an anti-clear function to properly drive its outputs during startup, minimising turn-on transients and improving system stability. Once the device has started, the pulse skipping technique allows the TPS54040DGQR to reduce output voltage ripple as it dynamically modulates the switching frequency in overlapping intervals between the minimum and maximum frequency.Advantages and Features
The TPS54040DGQR offers a highly efficient solution with excellent thermal performance, incorporating a wide-input voltage range between 4.5V and 18V and a flexible operating frequency range of 600kHz to 2.2MHz, which allows it to provide both high and low voltage outputs.In addition, the TPS54040DGQR also features an adjustable current limit and an adjustable soft-start control to limit in-rush current and minimize output voltage overshoot during startup. The TPS54040DGQR provides a reliable solution for applications that require a high-density POL converter.Conclusion
The TPS54040DGQR is a high-performance synchronous buck converter from Texas Instruments\' SIMPLE SWITCHER® family, which was specifically designed for high-current applications. With its wide input voltage range and adjustable operating frequency, the TPS54040DGQR provides exceptionally efficient and thermally-stable performance. The device also features protective functions such as an adjustable current limit, an adjustable soft-start control, and an anti-clear function. Due to its high-performance and wide range of features, the TPS54040DGQR is ideal for storing and distributing low-voltage point-of-load (POL) power.
