The TPS54073PWPR is a high-efficiency, low-loss synchronous-rectified buck DC/DC converter. This integrated circuit provides a regulated output voltage for applications such as portable equipment and battery-operated systems. It is optimized for the demands of mobile applications, with high efficiency and low standby current.

The TPS54073PWPR is part of the Power Management Integrated Circuits (PMICs) family of voltage regulators. PMICs serve as direct replacements for externally regulated linear, low-dropout (LDO) and switching regulators. PMICs are integrated circuits, incorporating multiple voltage regulation and protection functions in a single package.

The TPS54073PWPR is a DC/DC switching regulator. Switching regulators consist of a voltage regulator, an input power switch, an error amplifier, and feedback components, all arranged in a feedback loop. This loop contains a feedback resistor and an output capacitor, to serve as a storage reservoir. When the output voltage is greater than the desired value, the regulator current flows to ground. When the output voltage is less than the desired value, the error amplifier sends out a signal to the power switch to turn it on, and the output capacitor stores the charge. This cycle continues until the output voltage equals the desired value.

The voltage regulator of the TPS54073PWPR provides an adjustable output from 0.8V to 5V. The device has an integrated 8-bit SAR ADC for output voltage monitoring, and can achieve a conversion efficiency of up to 95%. The switching frequency of the device is adjustable, and it can operate in either pulse-width-modulation (PWM) or pulse-frequency-modulation (PFM) mode.

The TPS54073PWPR also features a thermal protection circuit, to protect the device from overheating. The package includes two external components, an input and output capacitor, as well as an integrated boot detector, which helps reduce the startup current. The device is also capable of operating in an ambient temperature range of -40°C to +85°C.

The TPS54073PWPR is a versatile and robust DC/DC switching regulator for applications requiring highly adjustable and efficient voltage regulation. This device can be used in a wide range of applications, such as industrial control and robotics, distributed power solutions, and mobile device power regulation.
