FeaTures

DescripTion

Complete Switch Mode Power Supply

The LTM4611 is a high density 15A output, switch mode

DC/DC buck converter power supply capable of operating

fromverylowvoltageinputsupplies. Includedinthepack-

age are the buck switching controller, power FETs, induc-

tor and loop-compensation components. The LTM4611

delivers up to 15A continuous current at high efﬁciency

Input Voltage Range: 1.5V to 5.5V

15A DC Output

Output Voltage Range: 0.8V to 5V

from an input voltage of 1.5V up to 5.5V . The output

Current Mode Control/ Fast ꢁransient Response

voltage is set between 0.8V and 5V by a resistor. Only a

few input and output capacitors are needed.

Parallel Multiple LꢁM^®4611s for Current Sharing

Highswitchingfrequencyandacurrentmodearchitecture

enable a very fast transient response to line and load

changes without sacriﬁcing stability. The device supports

frequency synchronization, multiphase/current sharing

operation, Burst Mode operation and output voltage

tracking for supply rail sequencing.
