LTM4619IV#PBF

LTM4619 is a complete dual 4A or single 8A stepdown DC/DC µModule® (micromodule) regulator. Included in the package are the switching controller, power FETs, inductor, and all support components. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The two outputs are interleaved with 180° phase to minimize the ripple noise and reduce the I/O capacitors. This device supports frequency synchronization and output voltage tracking for supply rail sequencing. Burst Mode operation or pulse skipping mode can be selected for light load operations. Fault protection features include overvoltage protection, overcurrent protection and foldback current limit for short-circuit protection. It is widely used in applications such as telecom and networking equipment, servers, storage cards, ATCA cards, industrial equipment, point of load regulation.
