LTM4705IY#PBF

LTM4705 is a complete dual 5A step-down switching mode µModule® (micromodule) regulator. Included in the package are the switching controller, power MOSFETs, inductor and support components. Its high efficiency design delivers dual 5A continuous output current. Only a few ceramic input and output capacitors are needed. This device supports selectable Burst 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 input overvoltage, output overcurrent and overtemperature protection. It is used in application such as general purpose point-of-load conversion, telecom, networking and industrial equipment, medical diagnostic equipment, test and debug systems etc.
