TPS53219ARGTT

DC DC Switching Controllers Overview

The TPS53219ARGTT is a single synchronous step-down controller from Texas Instruments, designed for wide input voltage applications. It operates within an input range of 4.5V to 25V and supports a fixed switching frequency of 500kHz. The device delivers up to 40A output current with an adjustable output voltage range of 600mV to 5.5V. It utilizes D-CAP and Eco-Mode topologies for high efficiency. The component functions in temperatures from -40°C to +85°C and is housed in a 16-VQFN (3x3) package.

DC DC Switching Controllers Feature Summary

• Integrates D-CAP and Eco-Mode control architectures for optimized transient response and light-load efficiency.
• Features synchronous rectification with integrated driver stages for the external power MOSFETs.
• Includes comprehensive protection mechanisms such as over-current protection and thermal shutdown.
• Supports programmable soft-start and frequency synchronization capabilities.

DC DC Switching Controllers Applications

• Point-of-load regulation for central processing units
• Memory subsystem power delivery
• Industrial equipment power distribution
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ARGTT' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and pinout configurations before integration. Cross-reference ordering information with authorized distributors to validate part authenticity and supply chain integrity.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high current density and wide input voltage flexibility. Evaluate thermal management requirements due to the 40A capability and VQFN package size. Confirm that the 500kHz switching frequency aligns with passive component selection constraints. Verify that the application does not require PMBus communication, which is reserved for the TPS53819 variant.

DC DC Switching Controllers Part Context

This component belongs to the TPS53219 family of single-phase synchronous buck controllers. It shares architectural similarities with the TPS53819 but lacks digital interface capabilities. The device is intended for general-purpose high-efficiency power conversion where analog control is sufficient.

DC DC Switching Controllers Replacement Considerations

The TPS53219RGTR is a documented alternative within the same product family offering identical electrical characteristics. Verify package marking and reel specifications when substituting.
