TPS54315PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54315PWPR is a high-performance synchronous buck converter from the SWIFT™ family. It is designed to operate with an input voltage range of 3V to 6V and can deliver a continuous output current of up to 3A. The device features a fixed output voltage of 2.5V with high initial accuracy.

 

Key electrical characteristics include a typical idle current of 6.2mA and a maximum duty cycle of 90%. The switching frequency can be set to 350kHz or 550kHz. The integrated MOSFET switches have a low resistance of 60mΩ, contributing to high efficiency. The converter includes features such as Enable and Power Good signals, and synchronous rectification.

 

Packaged in a 20-pin HTSSOP, the TPS54315PWPR is suitable for surface mount applications. Its integrated solution reduces board area and component count, making it an efficient choice for power supply designs requiring a compact and reliable step-down voltage conversion. The operating temperature range is -40°C to 85°C.
