The LTM4618EV 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 LTM4618EV 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 LTM4618EV is offered in 9mm × 15mm × 4.32mm LGA and 9mm × 15mm × 4.92mm BGA packages with RoHS compliant terminal finish.
