TPS54312PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54312PWPR is a member of the SWIFT family of DC-DC regulators. This synchronous buck converter integrates all required active components, including MOSFET switches, for high efficiency.

 

Key electrical specifications include an input voltage range of 3V to 6V and a fixed output voltage of 1.2V. It can deliver up to 3A of continuous output current. The device operates with fixed PWM frequencies of 350kHz or 550kHz, or an adjustable frequency from 280kHz to 700kHz. It features 60mΩ MOSFET switches for high efficiency and has an initial accuracy of 1.0% for its fixed output voltage.

 

The TPS54312PWPR is designed for low-voltage, high-density systems. Its integrated solution reduces board area and total cost. It is protected by peak current limit and thermal shutdown.

 

Packaged in a 20-pin HTSSOP (PWP) with a Surface Mount type, this component is suitable for applications requiring efficient power conversion in a compact form factor.
