9mm × 15mm × 4.32mm LGA Package
The LTM ? 4618 is a complete 6A output switching mode
DC/DC power supply in a 9mm × 15mm × 4.32mm LGA
package. Included in the package are the switching con-
troller, 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 ef?ciency
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 sacri?cing stability. The device supports
frequency synchronization and output voltage tracking for
supply rail sequencing. Burst Mode operation or pulse-
skipping mode can be selected for light load operations.
