TPS5130PTRG4

The TPS5130PTRG4 is a robust, integrated power modules (PMICs) designed to provide 3.3V to 5.5V output and regulate currents of up to 5A. It is used in a wide range of applications including and not limited to USB chargers, set-top boxes, and other various consumer products using point-of-load (POL) power supplies. Compared to the traditional DC/DC converters, the TPS5130PTRG4 works as a buck-boost power supply that provides integrated Proportional-Integral-Derivative (PID) loop control to regulate output voltage. Additionally, with its switch-mode design, the TPS5130PTRG4 also offers a very low-standby power consumption and improved efficiency when compared to linear voltage regulators of similar power levels.

The TPS5130PTRG4 is designed to provide 3.3V to 5.5V and up to 5A of output current. It does this via a buck-boost design that uses current sense resistors and an integrated variable-duty cycle controller to regulate output voltage. In this design, a power switch is used to control the current flowing through an inductor to achieve the desired output voltage.

The variable-duty cycle controller works by regulating the switch to regulate the current flowing through the inductor, which in turn affects the output voltage. The controller compares the feedback signal from the current sense resistors to the reference voltage that is set by the user. If the feedback signal is higher than the reference voltage, the switch is turned off, thus reducing the current flowing through the inductor and bringing the output voltage back to the reference voltage. On the other hand, if the feedback signal is below the reference voltage, the switch is turned on, thus increasing the current flowing through the inductor and bringing the output voltage up to the reference voltage.

Additionally, the TPS5130PTRG4 has built-in current limit protection that limits the current flowing through the inductor in the event of an overload condition. This prevents the output voltage from overshooting and damaging the connected load.

The TPS5130PTRG4 is a PMIC with many applications. It is used in USB chargers, set-top boxes, and other various consumer products that require high currents with a regulated voltage output. The high current capabilities and integrated PID loop controllers make it ideal for use as a Point-of-Load (POL) power supply, allowing users to avoid the complexity of designing a traditional DC/DC converter.

The TPS5130PTRG4 also offers a small footprint, making it ideal for applications with limited space. Its switch-mode design offers low standby power consumption and improved efficiency when compared to traditional linear voltage regulators. It has built-in current limit protection and overvoltage protection to protect the connected load in the event of an overload condition.

Overall, the TPS5130PTRG4 is a highly versatile PMIC that can be used in a wide range of applications requiring high current and/or a regulated output voltage. It is ideal for use as a Point-of-Load (POL) power supply, enabling users to avoid the complexity of designing a traditional DC/DC converter.
