Description

General part information

LTM4642 Series

The LTM4642 is a complete dual 4A or single 8A step-down DC/DC μModule®(micromodule) regulator. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over input voltage ranges of 4.5V to 20V, (2.375V min with external CPWR bias), the LTM4642 supports two outputs with voltage ranges of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 4A continuous current (5A peak) for each output.High switching frequency and a valley current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The two outputs are interleaved with 180° phase to minimize the ripple noise and reduce the I/O capacitors.The power module is offered in a 9mm × 11.25mm × 4.92mm BGA package. The LTM4642 is RoHS compliant with Pb-free finish.ApplicationsTelecom and Networking EquipmentServersFPGA Power
