The LTM4648 is a 10A low VIN step-down DC/DC μModule® (micromodule) regulator. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 2.375V to 5.5V, the LTM4648 supports an output voltage range of 0.6V to 5V, set by a single external resistor. This high efficiency design delivers up to 10A continuous current. Only bulk input and output capacitors are needed.

High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, programmable multiphase operation and output voltage tracking for supply rail sequencing.

Fault protection features include overvoltage protection, overcurrent protection and thermal shutdown. The LTM4648 is offered in a small 9mm × 15mm × 4.92mm BGA package available with SnPb or RoHS compliant terminal finish. For up to 16VIN operation, see the LTM4649.
