The LTM®4618 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.
