Analog Devices Inc. LTM4670 Quad μModule® Regulator

Analog Devices Inc. LTM4670 Quad μModule® Regulator is a DC/DC step-down micromodule regulator with 10A per output. Outputs can be paralleled in an array for up to 40A capability. The package includes the switching controller, power MOSFETs, inductor, and all support components. By operating over an input voltage range of 2.25V to 5.5V, each output voltage ranges from 0.5V to VIN set by only one external resistor. Its high-efficiency design delivers a 10A continuous output current per channel. Only a few input and output capacitors are needed.

The Analog Devices Inc. LTM4670 employs a Silent Switcher®2 architecture with internal hot loop bypass capacitors to achieve low EMI and high efficiency. The default frequency is internally set to 2MHz, and 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 lead free and RoHS compliant.
