TPS54313PWPRG4 Application Field and Working Principle

The TPS54313PWPRG4 is a synchronous switching regulator, which belongs to the PMIC (Power Management IC) Voltage Regulators DC DC Switching Regulators family. Advancing the power consumption benefits of TI\'s flagship products, it is designed to offer improved efficiency and accuracy over traditional DC-DC converters in space-constrained applications like computing and networking, communication, and consumer electronics.

In terms of application, the TPS54313PWPRG4 operates in a variety of configurations. It can be used as a step-down converter or as an inverter with load current up to 6.A. Its wide input voltage range of 6V to 22V supports PoE (Power over Ethernet) module input to provide regulated 9A output for high-performance wireless LAN. It can also be used to provide a constant current source for power LED and lamp circuits. Notably, the TPS54313PWPRG4 also features a high-efficiency operation in mobile devices, making it an ideal choice for applications such as automotive, consumer, industrial and computing.

One of the two main features of the TPS54313PWPRG4 is its Low-Noise Pulse-Switching Operation (LNPSO). This feature utilizes the duty cycle of the output voltage to regulate the accuracy of output voltage. With LNPSO, the TPS54313PWPRG4 can reduce EMI noise, which is typically generated by pulse-width modulating and switching voltage regulators, while still providing excellent accuracy. The second feature is its high-speed current-mode control, which ensures that the output voltage is always kept in regulation even as the input voltage varies.

The TPS54313PWPRG4 includes a differential control loop to increase performance and speed up transient response times. The differential control loop monitors and compares the voltage across the converter\'s output inductor to the internal reference voltage. At the same time, it takes into account other factors such as the load level and input voltage, allowing the control loop to adjust the output voltage accordingly.

The TPS54313PWPRG4 is a high-performance switching regulator device that provides both user convenience and energy efficiency for a wide range of applications. This device is ideal for applications where accuracy, small size, and low noise are essential, such as computing and networking, communication, and consumer electronics.
