The LTM^®4616 is a complete dual 2-phase 8A per channel
switch mode DC/DC power regulator system in a 15mm
× 15mm surface mount LGA or BGA package. Included
in the package are the switching controller, power FETs,
inductor and all support components. Operating from an
input voltage range of 2.7V to 5.5V, the LTM4616 supports
two outputs within a voltage range of 0.6V to 5V, each set
by a single external resistor. This high efficiency design
delivers up to 8A continuous current (10A peak) for each
output. Only bulk input and output capacitors are needed,
depending on ripple requirement. The part can also be
configured for a 2-phase single output at up to 16A.
The low profile package enables utilization of unused space
on the back side of PC boards for high density point-of-
load regulation.
Fault protection features include overvoltage protection,
overcurrent protection and thermal shutdown. The power
module is offered in space saving and thermally enhanced
15mm × 15mm × 2.82mm LGA and 15mm × 15mm ×
3.42mm BGA packages. The LTM4616 is RoHS compliant
with Pb-free finish.
