LTM4624IY#PBF

LTM4624 is a complete 4A step-down switching mode µModule® (micromodule) regulator. Included in the package are the switching controller, power FETs, inductor and support components. Its high efficiency design delivers 4A continuous, 5A peak, output current. 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. Fault protection features include overvoltage, overcurrent and overtemperature protection. It is used in applications such as telecom, datacom, networking and industrial equipment, medical diagnostic equipment, data storage rack units and cards, test and debug systems etc.
