Product Summary

The LTC1435ACS is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using a fixed frequency architecture. The operating current level of LTC1435ACS is user-programmable via an external current sense resistor. Wide input supply range allows operation from 3.5V to 30V (36V maximum). Applications of the LTC1435ACS include: Notebook and Palmtop Computers, PDAs; Cellular Telephones and Wireless Modems; Portable Instruments; Battery-Operated Devices; DC Power Distribution Systems.
