LTM4625IY

LTM®4625 is a complete step-down DC/DC switching mode µModule (micromodule) regulator. This LTM4625 supports an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers up to 5A continuous output current. Included in the package are the switching controller, power FETs, inductor and support components. Only bulk input and output capacitors are needed. It supports selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability. Typical applications are telecom, datacom, networking and industrial equipment, medical diagnostic equipment, data storage rack units and cards, test and debug systems.
