PMIC - Voltage Regulators - DC DC Switching Regulators

The TPS54380PWPR is a synchronous step-down DC/DC switch mode regulator with power stage (PMIC) from Texas Instruments. This regulator can be used in a variety of applications, from portable electronic products to adapter AC/DC systems.

The main features of this PMIC include: voltage conversion of up to 4.5A continuous current at 6Vin to 3Vout, up to 5.3Vin to 1.8Vout, up to 97.1% efficiency, a wide supply voltage range of 3V to 28V, operation at 100kHz, a high voltage mode, pulse skip mode and pulse spreading mode operation, low ripple, 1.5μA typical quiescent current, low current shutdown mode, over temperature and over current protection, and thermal shutdown.

The Working Principle of the TPS54380PWPR is similar to that of other typical DC/DC switching regulators. It starts by using a current switch to transfer energy from input voltage to the output voltage, which is then regulated and controlled by varying the frequency of the switch. The regulator works by applying a voltage feedback circuit to sense the output voltage, and comparing it to a reference voltage. To ensure high efficiency, the switch module is designed to ensure that the output current never falls below the reference current.

The Application Field of the TPS54380PWPR PMIC is quite wide, and it can be used in a variety of applications, such as in power supply systems for computers, servers, home electronics, industrial systems, LED lighting, medical electronics, and many more. This PMIC can also be used as an internal power supply for digital devices, as an AC/DC regulator in adapters, as a power source in automotive systems, and as a power adaptor for telecom systems. The advantages of using this PMIC are that it is small in size, efficient, and reliable.

In conclusion, the TPS54380PWPR is a synchronous step down DC/DC switch mode regulator from Texas Instruments which has numerous applications. The main features of this PMIC include wide input voltage range, high efficiency, low quiescent current, and various safety features. It is suitable for use in applications such as power supply systems, adapter AC/DC systems, LED lighting, and many more.
