TPS548D22RVFT is a DC DC buck switching regulator from Texas Instruments which is classified as part of the PMIC (Power Management Integrated Circuit) Voltage Regulators category, and more specifically the DC DC Switching Regulators sub-category. This integrated switch-mode regulator is designed to be used in a wide range of medium to high power applications such as home appliances, general electric motors, smart meters, robotics, and other industrial applications.

The main features of TPS548D22RVFT are its high-efficiency switching transistor, 3A low RDS(on), low ESR through inductor ripple current noise, current limit of30mA typical, thermal protection, overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP) and OVP protection. The package of TPS548D22RVFT is 45VQFN.

The working principle of the TPS548D22RVFT is that when DC voltage is supplied to the device, the switch FET is turned on and the inductor current increases, so the output voltage is increased. When the inductor current reaches the current limit, the switch FET is turned off and the inductor current returns to its initial state. This process is repeated in a cycle and the output voltage is maintained at the regulated set value.

The TPS548D22RVFT is designed to work within a wide input voltage range of 7V to 45V and a wide output voltage range of 0.8V to 5.5V. It supports a wide operating frequency range of 200kHz to 2MHz and a wide temperature range of -40°C to +85°C. The device also features a Dynamic Voltage Scaling (DVS) mode which enables the output voltage to be adjusted dynamically to optimize the efficiency of the system in response to changing load conditions. The device is also equipped with a programmable discreet voltage feed-forward mechanism which enables the device to respond faster to load changes and reduce the input voltage ripple.

The minimum operating voltage of TPS548D22RVFT is 7V, which is relatively low compared to other comparable products on the market. The high efficiency of this device also makes it a good viable choice for low power applications. With a temperature range of -40°C to +85°C, this makes the device suitable for applications that operate in extreme temperatures. The device is also equipped with many protection features such as thermal protection, overvoltage protection, undervoltage protection, overcurrent protection and over temperature protection. This ensures that the device will always run safely and reliably even in the most demanding applications.

The TPS548D22RVFT is an ideal solution for a wide range of medium to high power applications such as home appliances, general electric motors, smart meters, robotics and other industrial applications. With its wide input voltage range of 7V to 45V, wide output voltage range of 0.8V to 5.5V, wide operating frequency range of 200kHz to 2MHz, wide temperature range of -40°C to +85°C, high efficiency and multi-protection features, this device can easily meet the needs of most any application needing a high power DC DC switch-mode regulator.
