LTM4602

6A High Efﬁciency

DC/DC µModule

FEATURES

DESCRIPTION

Complete Switch Mode Power Supply

The LTM^®4602 is a complete 6A DC/DC step down power

supply. Included in the package are the switching control-

ler, power FETs, inductor, and all support components.

Operating over an input voltage range of 4.5V to 20V, the

LTM4602 supports an output voltage range of 0.6V to 5V,

setbyasingleresistor. Thishighefﬁciency design delivers

6A continuous current (8A peak), needing no heat sinks or

airﬂow to meet power speciﬁcations. Only bulk input and

output capacitors are needed to ﬁnish the design.

Wide Input Voltage Range: 4.5V to 20V

6A DC, 8A Peak Output Current

0.6V to 5V Output Voltage

1.5% Output Voltage Regulation

Ultrafast Transient Response

Current Mode Control

Pb-Free (e4) RoHS Compliant Package with Gold-

Pad Finish

Pin Compatible with the LTM4600

The low proﬁle package (2.8mm) enables utilization of

unused space on the bottom of PC boards for high density

point of load regulation. High switching frequency and an

adaptiveon-timecurrentmodearchitectureenablesavery

fast transient response to line and load changes without

sacriﬁcing stability. Fault protection features include

integrated overvoltage and short circuit protection with

a defeatable shutdown timer. A built-in soft-start timer is

adjustable with a small capacitor.

Up to 92% Efﬁciency

Output Overvoltage Protection

Optional Short-Circuit Shutdown Timer
