# TPS54972PWPR Product Series Introduction
## 1. Overview
The TPS54972PWPR is a highly efficient and versatile power management integrated circuit (PMIC) belonging to Texas Instruments' TPS54972 product series. This device is specifically designed to meet the demanding power requirements of a wide range of applications, offering a comprehensive solution for voltage regulation and power conversion.
## 2. Key Features
### High - Efficiency Operation
- The TPS54972PWPR utilizes advanced synchronous buck converter technology, which enables it to achieve high conversion efficiencies. This is crucial in applications where power consumption needs to be minimized, such as battery - powered devices or energy - sensitive systems. By reducing power losses during the conversion process, it helps to extend battery life and lower overall system operating costs.
- It can operate with efficiencies of up to 95% under typical load conditions, ensuring that a large portion of the input power is effectively transferred to the output, resulting in less wasted energy in the form of heat.
### Wide Input and Output Voltage Ranges
- **Input Voltage Range**: It supports a wide input voltage range, typically from 4.5V to 17V. This flexibility allows it to be used in various power supply scenarios, whether it is powered by a standard 5V USB source, a 12V power adapter, or other power sources within the specified range.
- **Output Voltage Range**: The output voltage can be adjusted from 0.8V to 5.5V, making it suitable for powering a diverse set of components, including microcontrollers, digital signal processors (DSPs), and other integrated circuits that require different supply voltages.
### High - Current Output Capability
The device is capable of delivering a continuous output current of up to 6A. This high - current output makes it suitable for powering power - hungry components such as high - performance processors and graphics chips. It can handle sudden load changes effectively, ensuring stable power delivery even under dynamic operating conditions.
### Integrated Protection Features
- **Over - Current Protection (OCP)**: The TPS54972PWPR is equipped with over - current protection to safeguard the device and the connected load from excessive current. In case of a short - circuit or an over - load condition, the OCP feature will automatically limit the output current to a safe level, preventing damage to the components.
- **Over - Voltage Protection (OVP)**: It also includes over - voltage protection to protect the load from excessive output voltage. If the output voltage exceeds the specified limit, the OVP circuit will take action to regulate the voltage and prevent potential damage to the connected devices.
- **Thermal Shutdown**: To prevent overheating, the device has a thermal shutdown feature. When the internal temperature of the TPS54972PWPR rises above a certain threshold, the thermal shutdown circuit will disable the device until the temperature drops to a safe level.
### Adjustable Switching Frequency
The switching frequency of the TPS54972PWPR can be adjusted from 200kHz to 2.5MHz. This flexibility allows designers to optimize the performance of the power supply based on the specific requirements of the application. A higher switching frequency can reduce the size of the external passive components, such as inductors and capacitors, leading to a more compact power supply design. On the other hand, a lower switching frequency can improve the efficiency at light loads.
## 3. Package and Pinout
The TPS54972PWPR comes in a 20 - pin HTSSOP (Thin Shrink Small Outline Package) package. This package offers several advantages, including good thermal performance and ease of PCB (Printed Circuit Board) assembly. The pinout of
