Product Summary

The LTC3701EGN is a 2-phase dual constant frequency current mode step-down DC/DC controller providing excellent load and line regulation. Power loss and noise due to ESR of the input capacitor are minimized by operating the two controller output stages out-of-phase. The applications of the LTC3701EGN include One or Two Lithium-Ion Powered Applications, Notebook and Handheld Computers, Personal Digital Assistants, Portable Instruments and Distributed DC Power Systems.
