Product Summary

The LTC1735CGN is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using a fixed frequency architecture. The operating frequency (synchronizable up to 500kHz) of the LTC1735CGN is set by an external capacitor allowing maximum flexibility in optimizing efficiency. The applications of the LTC1735CGN are Notebook and Palmtop Computers, PDAs, Cellular Telephones and Wireless Modems, DC Power Distribution Systems.
