DescripTion
The
LTM
®
4607
is a high efficiency switching mode buck-
boost power supply. Included in the package are the
switching controller, power FETs, and support components.
Operating over an input voltage range of 4.5V to 36V, the
LTM4607 supports an output voltage range of 0.8V to
24V, set by a resistor. This high efficiency design delivers
up to 5A continuous current in boost mode (10A in buck
mode). Only the inductor, sense resistor, bulk input and
output capacitors are needed to finish the design.
The low profile package enables utilization of unused space
on the bottom of PC boards for high density point of load
regulation. The high switching frequency and current
mode architecture enable a very fast transient response
to line and load changes without sacrificing stability. The
LTM4607 can be frequency synchronized with an external
clock to reduce undesirable frequency harmonics.
Fault protection features include overvoltage and foldback
current protection. The DC/DC µModule

regulator is
offered in a small thermally enhanced 15mm

compliant.
