The TPS5401DGQT is a step-down DC-DC switching regulator designed to increase battery life while maintaining high performance. The TPS5401DGQT is a non-synchronous buck switch regulator with a wide input voltage range, programmable cycle-by-cycle current limit, and over-voltage protection to help prevent catastrophic faults. In addition, the TPS5401DGQT is capable of delivering up to 4 A of continuous current and 8 A of peak current making it an ideal solution for space limited or high-current applications.
Application Field
The TPS5401DGQT is a DC-DC switching voltage regulator that can be used for a variety of applications including: mobile devices, microprocessors, FPGAs, ASICs, MCUs, and others. This device is especially well suited for handheld devices, such as smartphones, tablets and wearables, as it helps to reduce board space and power consumption. The wide input voltage range of the TPS5401DGQT (4.5 V to 30 V) makes it suitable for a broad range of applications and operating environments. This includes automotive, industrial and medical applications that often see wide or unpredictable voltage level fluctuations. The TPS5401DGQT is also able to provide up to 800 mA of continuous output current and support up to 8 A of peak current, which makes it suitable for even the most power-hungry applications.Working Principle
The TPS5401DGQT is a step-down DC-DC switching regulator that works through the process of pulse width modulation (PWM). In this process, a switch controlled by an internal oscillator is used to chop up the voltage coming from the input source and then, through the use of an inductor, filter out the resulting pulse. The output voltage is then adjusted depending on how long this “on-off” cycle is allowed to take place. The TPS5401DGQT is designed to switch at a fixed frequency of up to 2.2MHz in order to reduce power losses during the switching process. This also allows the use of smaller filter components, and therefore, a smallering package size. The TPS5401DGQT is also designed to have programmable cycle-by-cycle current limit, over-voltage protection and thermal shutdown protection, which helps to protect the device and its components from failure.Conclusion
The TPS5401DGQT is a DC-DC step-down switching regulator designed for a wide range of applications. It is capable of delivering up to 4 A of continuous current, as well as 8 A of peak current, making it suitable for even the most power-hungry applications. It has a wide input voltage range and is capable of switching at up to 2.2MHz to reduce power losses. In addition, the TPS5401DGQT features programmable cycle-by-cycle current limit, over-voltage protection and thermal shutdown protection to help protect the device and its components.The specific data is subject to PDF, and the above content is for reference
