The LTM4611IV#PBF is a high density 15A output, switch mode DC/DC buck converter power supply capable of operating from very low voltage input supplies. Included in the package are the buck switching controller, power FETs, inductor and loop-compensation components. The LTM4611IV#PBF delivers up to 15A continuous current at high efficiency from an input voltage of 1.5VIN up to 5.5VIN. The output voltage is set between 0.8V and 5V by a resistor. Only a few 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, multiphase/current sharing operation, Burst Mode operation and output voltage tracking for supply rail sequencing.
The LTM4611IV#PBF is available in a thermally enhanced 15mm × 15mm × 4.32mm LGA package. The LTM4611IV#PBF is PB-free and RoHS compliant.
