TPS54331D Description

Short technical summary and product information.

The TPS54331D from Texas Instruments is a 28V, 3A non-synchronous buck converter designed for efficient power management. It integrates a low RDS(on) high-side MOSFET, rated at 80 mΩ, supporting continuous output currents up to 3A. The device features an adjustable output voltage down to 0.8V and a fixed switching frequency of 570kHz.

 

To enhance efficiency, particularly at light loads, the TPS54331D incorporates a pulse-skipping Eco-mode™. Its low shutdown quiescent current of 1µA makes it suitable for battery-powered applications. The converter includes protection features such as cycle-by-cycle current limit, frequency foldback, and thermal shutdown.

 

Available in an 8-pin SOIC package, the TPS54331D is designed for applications including consumer electronics, industrial power supplies, and automotive audio systems. Its input voltage range is from 3.5V to 28V.
