The TPS5130PTG4 is a PMIC (power management integrated circuit) voltage regulator in the form of a linear + switching regulator. It is designed to provide power supply solutions for both external and internal power supply applications, and it also focuses on areas such as memory, CPU and GPU supply circuits of consumer electronics. Its external components are minimal, making it the ideal choice for applications that have the need for a compact, efficient and low input-output power solution.

TPS5130PTG4 provides an integrated adjustable linear regulator and a synchronous switching regulator to provide a power supply solution with a wide range of input-output voltages and currents. The output voltage and current capabilities of the linear regulator and the switching regulator can be set by two external resistors. It also features a wide input supply range from 6V to 36V and an output voltage range from 0.6V to 2.2V. Furthermore, the switching regulator can provide up to 4A maximum load current and has programmable ripple correction function.

The TPS5130PTG4 is also equipped with multiple safety features for added protection and reliability. It includes an over temperature protection (OTP) which grants a grace shutdown at 150 degrees Celsius. The TPS5130PTG4 also has a programmable soft-start which prevents inrush currents at start-up and a programmable UVLO (under voltage lockout) to prevent damage due to insufficient operating voltages. In addition, the device features an auto recovery feature which allows the power supply to continue from a safe state after the fault is cleared.

The working principle of the TPS5130PTG4 works by having a dual rail system with a switching regulator being used to regulate the voltage for the output rail. The linear regulator is then used to fine-tune the voltage on the output rail. The supply voltage is first adjusted by the switching regulator to the desired voltage level, and then the linear regulator compensates the small variations in the output voltage.

The TPS5130PTG4 is often found as popular power supply solution in a diverse range of applications including embedded system platforms, routers, microcontrollers, FPGAs and motor amplifiers. Its innovative dual rail system makes it a great choice for high power density and high efficiency applications. Its convenient configuration and robust safety features also make the TPS5130PTG4 a reliable power supply solution for many modern consumer electronics.
