TPS62142RGTR Application Field and Working Principle

The TPS62142RGTR, also known as a DC to DC switching regulator, is an efficient and low power PMIC (Power Management IC) unit manufactured and distributed by Texas Instruments. It has a wide range of applications in embedded systems, data processing and various industrial fields, and is effective at sourcing power for low current applications.

Functionality

The TPS62142RGTR is based on synchronous buck converters, which comprise of two main components: a control circuit and a power stage by which the control circuit controls the power stage to regulate the output voltage according to the input voltage. The control circuit is used for controlling the switching frequency of the power stage, while the power stage is used to amplify the input voltage, filter out the noise present in the input voltage, and ensure that an applicable output voltage is achieved.

Versatility

The TPS62142RGTR has an input voltage range of 4V to 21V, and an output voltage range of 0.5V to 7.3V. This wide range of available inputs and outputs allows for a variety of applications. The device also offers a low shut-down current and low quiescent current which makes it extremely useful for low current applications. With a switching frequency range of 250kHz to 1.2MHz, this device can be used for a range of applications from high frequency to low frequency.

Protection Circuits

In order to safeguard the device from any discrepancies, the TPS62142RGTR is built with protection circuits integrated into its design. The overvoltage protection circuit will disconnect the supply from the output stage when an overvoltage is detected, while the overtemperature protection circuit will shut down the device when an excessive rise in temperature is detected.

Performance

When it comes to performance, the TPS62142RGTR can deliver a maximum output current of 1.8A with a peak efficiency of 94%. This ensures that the device delivers a sufficient amount of power and the output voltage is accurately regulated. Additionally, the device also offers low output voltage ripple and low shutdown current, making it an ideal choice for low current applications.

Conclusion

As a whole, the TPS62142RGTR is an effective and low power DC-DC switching regulator that is perfect for a wide range of embedded applications. Its wide range of input and output voltages and low current requirements make it a great choice for applications where power and efficiency are of the utmost importance.
