The LTM4618 is a complete 6A output switch mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 4.5V to 26.5V, the LTM4618 supports an output voltage range of 0.8V to 5V set by a single external resistor. Its high efficiency design delivers 6A continuous current (8A peak). 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 and output voltage tracking for supply rail sequencing. Burst Mode operation or pulseskipping mode can be selected for light load conditions.
Fault protection features include overvoltage protection, overcurrent protection and foldback current limit for short-circuit protection.
The LTM4618 is offered in 9mm × 15mm × 4.32mm LGA and 9mm × 15mm × 4.92mm BGA packages with RoHS compliant terminal finish.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal. View our quality and reliability program and certifications for more information.

LTpowerCAD® is a power supply design program which selects power stage components, provides detailed power efficiency, shows quick loop Bode plot stability and load transient analysis, and can export to LTspice for simulation.
Demonstration circuit 1472 features the LTM4618EV μModule® regulator, a complete high efficiency synchronous buck regulator with tracking. The DC1472 input range is from 4.5V to 26.5V and is capable of delivering up to 6A of output current; however, current derating may be necessary under certain VIN, VOUT, frequency and thermal conditions. The output voltage is jumper programmable from 1.2V to 5V and can be set as low as 0.8V, the reference voltage of the LTM4618EV.
