LTM4627IV#PBF

LTM®4627 is a high efficiency switch mode DC/DC µModule regulator. Included in the package are the switching controller, power FETs, inductor and compensation components. LTM4627 supports an output voltage range of 0.6V to 5V, set by a single external resistor. Only a few input and output capacitors are needed. Current mode operation allows precision current sharing of up to four LTM4627 regulators to obtain 60A output. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, multiphase/current sharing operation, Burst Mode operation and output voltage tracking for supply rail sequencing. Applications are telecom servers and networking equipment, ATCA and storage cards, industrial equipment, medical systems.
