TPS51518RUKT Description

Short technical summary and product information.

The TPS51518RUKT from Texas Instruments is a single-phase D-CAP and D-CAP2 synchronous buck controller designed for applications requiring precise voltage regulation. It features a wide input voltage range of 3 V to 28 V and supports output voltages adjustable from 0.5 V to 2.0 V through a flexible 2-bit VID control.

 

This controller utilizes adaptive on-time modulation with selectable D-CAP and D-CAP2 modes, operating at 350 kHz for fast transient response or ultra-low ESR output capacitors. Key electrical features include differential voltage feedback, DC compensation for accurate regulation, and low-side RDS(on) current sensing with a temperature coefficient of 4700 ppm/°C.

 

Designed for ease of integration, the TPS51518RUKT offers programmable soft-start and output voltage transition times, along with built-in output discharge. It also includes essential protection features such as OVP, UVP, OCP, and non-latched thermal shutdown. The device is housed in a compact 3 mm x 3 mm, 20-pin WQFN package suitable for surface mounting.

 

Applications for the TPS51518RUKT include notebook computers, GFX supplies, and system agents for platforms like Intel Chief River, where multiple voltage levels and accurate regulation are critical.
