Product Summary

The TPS40090PW is a two-, three-, or four-phase programmable synchronous buck controller, optimized for low-voltage, high-current applications powered by a 5-V to 15-V distributed supply. A multi-phase converter offers several advantages over a single power stage including lower current ripple on the input and output capacitors, faster transient response toload steps, improved power handling capabilities, and higher system efficiency. The applications of the TPS40090PW include Internet Servers, Network Equipment, Telecommunications Equipment, DC Power Distributed Systems.
