The LTM4670 is a quad DC/DC step-down μModule®(micromodule) regulator with 10A per output. Outputs can be paralleled in an array for up to 40A capability. Included in the package are the switching controller, power MOSFETs, inductor and all support components. Operating over an input voltage range of 2.25V to 5.5V, each output voltage ranges from 0.5V to VINset by only one external resistor. Its high efficiency design delivers 10A continuous output current per channel. Only a few input and output capacitors are needed.The LTM4670 employs a Silent Switcher®2 architecture with internal hot loop bypass capacitors to achieve both low EMI and high efficiency. The default frequency is internally set to 2MHz, it can be externally synchronized to a clock from 1MHz to 2.6MHz.Fault protection features include overvoltage, overcurrent and overtemperature protection. The LTM4670 is Pb-free and RoHS compliant.APPLICATIONSTelecom, Networking and Industrial EquipmentMultirail Point-of-Load RegulationFPGAs, DSPs and ASICs Applications
