Product Summary

The ltc3735eg is a 2-phase synchronous step-down switching regulator controller that drives all N-channel power MOSFETs in a constant frequency architecture. The output voltage of the ltc3735eg is programmable by six VID bits during normal operation and by external resistors during initial boot-up and deeper sleep state. Applications are (1)Mobile and Desktop Computers; (2)Internet Servers.
