Product Summary

The TPS54310 is a low-input-voltage high-output-current synchronous-buck PWM converter. The TPS54310 integrates all required active components. The applications of the TPS54310 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 TPS54310 is available in a thermally enhanced 20-pin TSSOP (PWP) PowerPAD package, which eliminates bulky heatsinks.
