DESCRIPTION

The LTM

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

LTM4609 supports an output voltage range of 0.8V to

34V, set by a resistor. This high efﬁ ciency design delivers

up to 4A continuous current in boost mode (10A in buck

mode). Only the inductor, sense resistor, bulk input and

output capacitors are needed to ﬁ nish the design.

The low proﬁ le 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 sacriﬁ cing stability. The

LTM4609 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™ is offered in a

small thermally enhanced 15mm × 15mm × 2.8mm LGA

package. The LTM4609 is Pb-free and RoHS compliant.
