LTM4657IY#PBF

LTM4657 is a complete 8A step-down switching mode µModule (micromodule) regulator. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 3.1V to 20V, this device supports an output voltage range of 0.5V to 5.5V, set by a single external resistor. 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 application like telecom, datacom, networking and industrial equipment, medical diagnostic equipment, data storage rack units and cards, test and debug systems etc.

• Total DC output voltage error over line, load and temperature is ±1.5% maximum
