TPS51218DSCT Description

Short technical summary and product information.

The Texas Instruments TPS51218DSCT is a compact, single-channel buck controller utilizing adaptive on-time D-CAP mode. It 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.

 

This controller supports a wide input voltage range from 3V to 28V and can deliver an output voltage from 0.7V to 2.6V, with a maximum output current of 20A. Key features include Enable, Light-load efficiency, Power Good, Prebias startup, and Synchronous rectification. The D-CAP mode offers a fast load step response of 100 ns.

 

The TPS51218DSCT is available in a 10-WSON (3x3) package, designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The device integrates a boost switch and offers protection features like OVP/UVP/OCP and thermal shutdown.

 

This controller is ideal for applications requiring efficient power conversion and high current delivery in a small footprint. Its synchronous rectification capability enhances efficiency, making it a suitable choice for power-sensitive designs.
