TPS51219RTET Description

Short technical summary and product information.

The Texas Instruments TPS51219RTET is a high-performance, single synchronous step-down controller. It is designed to operate within a wide input voltage range of 3 V to 28 V, making it suitable for various power supply applications.

 

This controller features differential voltage feedback for accurate regulation and supports an output voltage range from 0.5 V to 2.0 V, with a maximum output current capability of 20 A. It utilizes adaptive on-time modulation with selectable control architectures and frequencies, including D-CAP mode at 300 kHz/400 kHz for fast transient response and D-CAP2 mode at 500 kHz/670 kHz for ceramic output capacitors.

 

The TPS51219RTET is housed in a compact 16-WQFN (3 mm x 3 mm) package, suitable for surface mounting. Key features include enable and power good signals, light load efficiency, pre-bias start-up, synchronous rectification, and internal soft-start. Protection features include overvoltage, undervoltage, and overcurrent protection, along with thermal shutdown.

 

This device is ideal for applications requiring efficient and stable DC/DC conversion, such as power supplies for computing, industrial, and consumer electronics where space and performance are critical.
