TPS54313PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54313PWPR is a member of the SWIFT family of DC-DC regulators. This synchronous buck converter integrates all required active components for efficient power conversion. It operates with an input voltage range of 3V to 6V and provides a fixed 1.5V output voltage, capable of sourcing and sinking up to 3A of continuous current.

 

The device features integrated 60mΩ MOSFET switches for high efficiency. It operates at fixed frequencies of 350kHz and 550kHz, with an adjustable range from 280kHz to 700kHz. The TPS54313PWPR includes internal compensation for a low parts count and offers fast transient response. Protection features include peak current limit and thermal shutdown.

 

Packaged in a 20-pin HTSSOP (PWP) with PowerPAD™, this component is designed for surface mounting. Its integrated solution helps reduce board area and total cost, making it suitable for low-voltage, high-density systems and point-of-load regulation for processors, FPGAs, and ASICs.
