TPS5130QPTRQ1

The TPS5130QPTRQ1 is a high-performance linear voltage regulator and switching voltage regulator with an integrated MOSFET switch to provide up to a 5A output via a single inductor. It is generally used for portable applications that require reliable, low-profile, power management solutions. It is designed to work with high-current, wide-input voltage applications, allowing the device to replace multiple step down converters, thus saving power and design time. This device is capable of efficiently regulating outputs in a wide-input range of 3.2V to 17V, with output voltage options ranging from 0.9V to 5V.

The TPS5130QPTRQ1 is an advanced power management solution that can provide up to 8A of total output current, combining both low-voltage linear and high-current switching regulatory technologies. It features a patented current sharing circuit and a programmable current limit circuit, enabling the device to deliver high operation efficiency in high-current applications. Moreover, the device contains test pins for consumer verification and an enable pin for power sequencing making it an ideal solution for portable consumer applications.

The current flowing through the output pin is controlled by a voltage regulation loop consisting of an internal error amplifier, a pulse density modulation (PDM) converter and a synchronous MOSFET switch. The load current is monitored by sensing the voltage across the external sense resistor. The voltage regulation loop usually maintains the output voltage within a few millivolts of the programmed value.

The device also has rest and power good options that can be used to monitor the output voltage of the device. When an output voltage falls below the programmed threshold, the device automatically sets the output to its minimum output voltage. The power down and power up sequencing can be programmed through the enable function of the device. In addition, the device features a programmable frequency for switching the internal MOSFET switch, which allows for flexibility and efficiency optimization.

The TPS5130QPTRQ1 is also equipped with various features to ensure system reliability, such as over-temperature protection, current limiting, under-voltage lockout, foldback current limit protection and thermal overload protection. The device also incorporates programmable switching frequency and phase synchronization, allowing it to work with multiple power supplies within the same system. This helps to minimize noise circulation in the system and reduce EMI interference.

Overall, the TPS5130QPTRQ1 is an excellent choice of regulator for portable consumer applications due to its high-performance combined linear and switching regulation, integrated MOSFET switch, and various safety features. Its high current ratings and wide operating temperatures makes it suitable for high-current applications and is designed to maximize efficiency and reduce power consumption. It can replace multiple step down converters and thus saves design time, while its low-profile form factor makes it ideal for portable applications.
