TPS51218DSCR Description

Short technical summary and product information.

The TPS51218DSCR from Texas Instruments is a compact, single-channel buck controller featuring adaptive on-time D-CAP mode. This device is suitable for low output voltage, high current applications, such as PC system power rails and point-of-load (POL) power supplies in digital consumer products.

 

Key electrical specifications include a wide input voltage range from 3V to 28V and an output voltage range of 0.7V to 2.6V. It supports a maximum output current of 20A and operates with a typical quiescent current of 0.00032A. The controller utilizes a D-CAP mode with a 100-ns load step response and adaptive on-time control architecture.

 

This controller is available in a 10-WSON (3x3) package and is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. Features include Enable, Light-load efficiency, Power Good, Prebias startup, and Synchronous rectification, making it a versatile solution for demanding power management needs.
