TPS75133QPWP Application Field and Working Principle

The TPS75133QPWP is a low-power, low-voltage, high-accuracy, adjustable output voltage regulator. It is intended for use in moderately powered devices such as microcontrollers, digital signal processors (DSPs), and FPGAs. The TPS75133QPWP is a Buck-Boost non-synchronous H-bridge regulator that provides both step-up and step-down voltage conversion capabilities in the same device. This makes it ideal for battery-powered systems that use multiple voltage sources, such as solar panels, or for systems that need to change their operating voltage depending on system requirements.

Features

The TPS75133QPWP has several features that set it apart from other linear regulators. The device is capable of step-up and step-down voltage conversion, meaning that it can regulate positive and negative voltages between 0.9V and 5.5V with an accuracy of +-1.5%. It has an adjustable output voltage, allowing the user to set the voltage at any voltage between 0.8V and 5.5V. The device also includes an over-voltage protection function, which prevents the output voltage from exceeding a set level to protect sensitive loads. The regulator also features adjustable current limiting and short-circuit protection.

Applications

The TPS75133QPWP is ideal for use in a variety of applications due to its flexibility and ease of use. It can be used to power low-power microcontrollers and DSPs, as well as FPGAs. It is also well-suited for portable applications, including those powered by a variety of different voltage sources. It can be used in automotive applications such as electronic fuel injection and electronic vehicles, as well as for powering communications systems, medical equipment, and many other products.

Design

The TPS75133QPWP is designed to provide an adjustable output voltage from 0.9V to 5.5V. It is based on an H-bridge topology, which allows the device to provide both step-up and step-down voltage conversion. The device is powered by a single input voltage (VIN) of between 4.5V and 28V, and contains an integrated storage capacitor. This capacitor is used to provide a low output impedance and allow for a wide input range.

Working Principle

The TPS75133QPWP operates on a simple step-up and step-down working principle. It uses two configurable switches to control the output voltage. These switches switch the output voltage between the input and output signals by alternately charging and discharging the storage capacitor. This switch control is achieved by configuring a resistor network between the input and output pins, allowing the output voltage to be both stepped up and stepped down.The TPS75133QPWP is a low-power, low-voltage, high-accuracy, adjustable output voltage regulator. It is capable of step-up and step-down voltage conversion and offers a wide range of features, making it ideal for a variety of applications. The device operates on an H-bridge topology and uses configurable switches to control the output voltage.
