LTM4604IV#PBF

LTM4604 is a complete 4A switch mode step-down µModule® (micromodule) regulator. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 2.375V to 5.5V, it supports an output voltage range of 0.8V to 5V, set by a single resistor. This high efficiency design delivers upto 4A continuous current (5A peak). Only bulk input and output capacitors are needed to complete the design. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. This device supports output voltage tracking for supply rail sequencing. Fault protection features include foldback current protection, thermal shutdown and a programmable soft-start function. It is used in application such as telecom and networking equipment, servers, ATCA cards, industrial equipment.
