TPS62745DSST Description

Short technical summary and product information.

The Texas Instruments TPS62745DSST is an active step-down (buck) DC/DC switching regulator. It operates with an input voltage range from 3.3V to 10V and can deliver up to 300mA of output current. This device features a typical quiescent current of 400 nA, making it suitable for low-power applications.

 

The TPS62745DSST supports selectable output voltages ranging from 1.8V to 3.3V, providing design flexibility. It utilizes a Constant on-time (COT) and DCS-Control mode for efficient operation. The regulator is housed in a compact 12-WSON (2x3 mm) package with an exposed pad, suitable for surface mounting.

 

Key features include adaptive/dynamic voltage scaling, enable functionality, light load efficiency, output discharge, power good output, and soft start. The device operates within a temperature range of -40°C to 125°C. Its synchronous rectification and up to 2.5MHz switching frequency contribute to its performance.
