TPS54312PWPRG4 Description

Short technical summary and product information.

The TPS54312PWPRG4 is a member of the SWIFT family of DC-DC regulators from Texas Instruments. This synchronous buck PWM converter integrates all required active components, offering a low-input-voltage, high-output-current solution.

 

Key electrical specifications include an input voltage range of 3V to 6V and a fixed output voltage of 1.2V. It can supply up to 3A of continuous output current. The device operates with a PWM frequency of 350kHz or 550kHz, with an adjustable range from 280kHz to 700kHz. It features 60mΩ MOSFET switches for high efficiency and has an initial output voltage accuracy of 1%.

 

The TPS54312PWPRG4 is designed for low-voltage, high-density systems and point-of-load regulation. Its integrated solution reduces board area and total cost. The operating temperature range is -40°C to 85°C.

 

This component is housed in a 20-pin HTSSOP package, specifically a 20-PowerTSSOP with a width of 4.40mm. It is designed for surface mount applications.
