The Texas Instruments TPS54331DDA is a non-synchronous buck converter designed for efficient power management. It integrates a low RDS(on) high-side MOSFET, supporting up to 3A of continuous output current.
This device operates within a wide input voltage range of 3.5V to 28V and allows for an adjustable output voltage down to 0.8V. It features a fixed switching frequency of 570kHz, simplifying external compensation. The TPS54331DDA includes an Eco-mode™ for high efficiency at light loads and a typical shutdown quiescent current of 1µA, making it suitable for battery-powered applications.
Protection features include cycle-by-cycle current limit, frequency foldback, and thermal shutdown. The TPS54331DDA is available in an 8-pin SOIC PowerPAD™ package, optimized for thermal performance, and is suitable for surface mount applications. Its adjustable slow-start feature helps limit inrush currents during power-up.
Applications for the TPS54331DDA include consumer electronics such as set-top boxes, LCD displays, and battery chargers, as well as industrial power supplies.
