Small 15mm × 15mm × 4.32mm LGA Package The LTM®4611 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 LTM4611
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 …
