DESCRIPTION

The LTM

ing mode DC/DC power supply. Included in the package

are the switching controller, power FETs, inductor, and all

support components. Operating over input voltage ranges

of 4.5V to 26.5V, the LTM4619 supports two outputs with

voltage ranges of 0.8V to 5V, each set by a single external

resistor. Its high efﬁ ciency design delivers 4A continuous

current (5A peak) for each output.

High switching frequency and a current mode architecture

enable a very fast transient response to line and load

changes without sacriﬁ cing stability. The two outputs are

interleaved with 180° phase to minimize the ripple noise and

reduce the I/O capacitors. 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.

Fault protection features include overvoltage protection,

overcurrent protection and foldback current limit for

short-circuit protection.

The low proﬁ le package (2.8mm) enables utilization of

unused space on the bottom of PC boards for high density

point of load regulation. The power module is offered in a

space saving and thermally enhanced 15mm × 15mm ×

2.8mm LGA package. The LTM4619 is Pb-free and RoHS

compliant.
