TPS51125RGETG4 application field and working principle
TPS51125RGETG4 belongs to PMIC - Voltage Regulators - DC DC Switching Controllers. It is a highlyintegrated single-stage Buck synchronous controller with power-saving mode. It can provide output voltage up to 5A, making it perfect for low-voltage applications.
The TPS51125RGETG4 controller integrates a synchronous rectifier (SR) driver and gate driver to drive two integrated power switches and a soft start network to minimize output ripple current. The device includes an internal 200 mV reference and a 1.0 MHz fixed frequency two-bit SPI (Serial Peripheral Interface) control loop, providing fast transient response and line and load regulation. The TPS51125RGETG4 can be used to design synchronous Buck regulators with an output voltage as low as 0.8 V.
Application fields
TPS51125RGETG4 is suitable for a variety of designs requiring low output voltage and high efficiency. Some potential application fields where this component can be used include:
- Data centers and cloud computing systems
- Battery-powered medical devices
- Graphics cards
- Power architecture processors
- Storage systems
Working Principle
The TPS51125RGETG4 consists of an input voltage rail, and consists of two synchronous rectifiers, an outer loop controller, and an internal comparator to generate an output voltage from it. The TPS51125RGETG4 controller also includes a Current Mode (CM) control loop, allowing it to synchronize the current and voltage of the rectifiers to a maximum switching frequency. This reduces average power losses and increases the efficiency of the power supply.
The controller also includes a PFM (Power Factor Modulation) control loop, which controls the switching frequency of the rectifiers between a minimum and maximum frequency based on the load current. This reduces the average power consumption, improving the efficiency of the power supply.
The TPS51125RGETG4 includes an internal Soft Start Circuit, which slowly brings the output voltage up to the desired value after power-up, minimizing inrush current. It also includes an Overvoltage Lockout (OVLO) Circuit, which can be used to unlock the power supply after an overvoltage event.
The TPS51125RGETG4 also includes two internal voltage references, which can be used to set the output voltage and the current limit of the power supply. The TPS51125RGETG4 also includes a slew rate control circuit, which can be used to adjust the switching frequency of the rectifiers for improved EMI filter performance.
The TPS51125RGETG4 also includes a single-wire serialized interface, allowing the controller to be monitored, configured and controlled remotely.
Conclusion
The TPS51125RGETG4 is a high-performance, highly-integrated single-stage buck synchronous controller with power-saving mode. It includes a number of features to improve the efficiency and performance of the power supply, including a Soft Start Circuit, PFM control loop and a Current Mode control loop. It also includes a single-wire serialized interface for remote monitoring, configuration and control.
