TPS54917RUVR Integrated Circuits (ICs)

PMIC - Voltage Regulators - DC DC Switching Regulators

DC-DC switching regulators are components that regulate DC voltages using switched-mode power supply topologies. This type of voltage regulation is popular for its high efficiency compared to linear voltage regulators. The TPS54917RUVR is an example of a DC-DC switching regulator from Texas Instruments. It is an synchronous buck switching regulator designed for applications requiring high current and output voltage accuracy.

The TPS54917RUVR is rated to supply up to 4.5A at a voltage range of 0.3V to 5.5V. This makes it suitable for a wide range of applications such as power amplifiers, processors, FPGAs, and other DC-DC requirements. This regulator supports a variety of input and output voltage adjustment methods as well as programmable soft start. It also has integrated EMI filters, giving it the capability to reduce EMI-induced noise to an acceptable level.

There are many applications suited to the TPS54917RUVR. It can be used in power amplifiers, microprocessors, FPGAs, and other DC-DC applications. It can also be used in automotive applications such as advanced driver assistance systems, onboard power systems, battery chargers, and powertrain control modules. Additionally, the TPS54917RUVR can also be used in low-power communication systems and medical applications.

The TPS54917RUVR works using synchronous buck converter technology to achieve the voltage regulation. It has two primary components, the switch and the inductor. The switch is used to selectively connect or disconnect the power supply to the load, and the inductor is used to smooth out the voltage provided by the power supply. This buck converter has an on-chip MOSFET and current sense amp, which enables regulated output voltage even under dynamic load.

The TPS54917RUVR also has a wide range of safety features. It has a Power Good signal, which indicates when the output voltage is stable, as well as an over-voltage, over-temperature, and short circuit protection. This makes the TPS54917RUVR suitable for applications that require high reliability and safety.

In summary, the TPS54917RUVR is a DC-DC buck switching regulator from Texas Instruments designed for high-current and output voltage accuracy applications. It is also highly reliable and has a wide range of safety features. It is suitable for use in power amplifiers, processors, FPGAs, automotive applications, and many other DC-DC requirements.
