Product Summary

The TPS54310PWP is a dc/dc regulator. The applications of the TPS54310PWP include Low-Voltage, High-Density Systems With Power Distributed at 5 V or 3.3 V, Point of Load Regulation for High Performance DSPs, FPGAs, ASICs, and Microprocessors, Broadband, Networking and Optical Communications Infrastructure and Portable Computing/ Notebook PCs. The TPS54310PWP is available in a thermally enhanced 20-pin TSSOP (PWP) PowerPAD. package, which eliminates bulky heatsinks. The device can provides evaluation modules and the SWIFT designer software tool to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
