TPS54314PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54314PWPR is a member of the SWIFT family of DC-DC regulators, designed as a low-input-voltage, high-output-current synchronous-buck PWM converter. It integrates all required active components, including 60-mΩ MOSFET switches for high efficiency.

 

This device provides a fixed 1.8V output voltage with 1.0% initial accuracy and can deliver up to 3A of continuous output current. The input voltage range is from 3V to 6V. It operates with a switching frequency of 350kHz or 550kHz, and can be adjusted from 280kHz to 700kHz. The TPS54314PWPR is protected by peak current limit and thermal shutdown.

 

Designed for low-voltage, high-density systems, it is suitable for point-of-load regulation in applications such as DSPs, FPGAs, ASICs, and microprocessors. The converter is housed in a thermally enhanced 20-pin HTSSOP (PWP) package, which is surface-mountable and reduces board area.

 

Key features include internal compensation for a low parts count, fast transient response, and integrated solution for reduced board area and total cost. It also includes Enable and Power Good features.
