TPS54312PWPG4 Description

Short technical summary and product information.

The TPS54312PWPG4 is a member of the SWIFT family of DC-DC regulators from Texas Instruments. This device is a low-input-voltage, high-output-current synchronous-buck PWM converter that integrates all required active components. It features 60-mΩ MOSFET switches for high efficiency and provides 3A of continuous output source and sink current.

 

This specific model, TPS54312PWPG4, offers a fixed output voltage of 1.2V with 1.0% initial accuracy. It operates with a switching frequency of 350kHz or 550kHz fixed, or adjustable from 280kHz to 700kHz. The device is designed for high-density systems and point-of-load regulation.

 

The TPS54312PWPG4 comes in a thermally enhanced 20-pin HTSSOP PowerPAD package, reducing board area and total cost. It is suitable for applications requiring efficient power conversion in a compact form factor, such as low-voltage systems distributed at 5V or 3.3V.
