Product Summary

The TPS40130RHBT is a two-phase synchronous buck controller that is optimized for low-output voltage, high-output current applications powered from a supply between 3 V and 40 V. A multi-phase con-verter offers several advantages over a single powerstage including lower current ripple on the input and soutput capacitors, faster transient response to load steps, improved power handling capabilities, andhigher system efficiency. The applications of the TPS40130RHBT include Graphic Cards, Internet Servers, Networking Equipment, Telecommunications Equipment, DC Power Distributed Systems.
