TPS54311PWP Description

Short technical summary and product information.

The TPS54311PWP is a member of Texas Instruments' SWIFT family of DC-DC regulators. This synchronous buck converter integrates all required active components, offering a 3A continuous output current capability. It operates with an input voltage range of 3V to 6V and provides a fixed 0.9V output.

 

Key electrical specifications include a 3A output current, 3V to 6V input voltage, and a fixed 0.9V output. The device features 60-mΩ MOSFET switches for high efficiency and operates at selectable switching frequencies of 350 kHz or 550 kHz, with an adjustable range from 280 kHz to 700 kHz. It also includes features like peak current limit and thermal shutdown for load protection.

 

Packaged in a 20-pin HTSSOP (PWP) with a PowerPAD™, this component is designed to reduce board area and total cost. The surface-mount package is suitable for high-density systems. The operating temperature range is -40°C to 85°C.

 

This converter is ideal for point-of-load regulation in high-performance DSPs, FPGAs, ASICs, and microprocessors, as well as in low-voltage, high-density systems powered at 5V or 3.3V.
