LTM4618

6A DC/DC µModule

Regulator with Tracking and

Frequency Synchronization

FEATURES

DESCRIPTION

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 efﬁciency

design delivers 6A continuous current (8A peak). Only a

few input and output capacitors are needed.

On-Board Frequency Synchronization

Selectable Burst Mode^®Operation

Highswitchingfrequencyandacurrentmodearchitecture

enable a very fast transient response to line and load

changes without sacriﬁcing stability. The device supports

frequencysynchronizationandoutputvoltagetrackingfor

supply rail sequencing. Burst Mode operation or pulse-

skipping mode can be selected for light load operations.

9mm × 15mm × 4.32mm LGA Package

APPLICATIONS

Fault protection features include overvoltage protection,

overcurrent protection and foldback current limit for

short-circuit protection.
