The LTM4611IV#PBF is a high density output switch mode DC/DC buck converter power supply µModule Regulator capable of operating from very low voltage input supplies. The LTM4611 delivers up to 15A continuous current at high efficiency from an input voltage of 1.5 up to 5.5VIN. The output voltage is set between 0.8 and 5V by a resistor. Only a few input and output capacitors are needed. High switching frequency and 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.
