LTM4605

High Efﬁciency

Buck-Boost DC/DC µModule

FEATURES

DESCRIPTION

The LTM^®4605 is a high efﬁciency switching mode buck-

boost power supply. Included in the package are the

switchingcontroller,powerFETs,andsupportcomponents.

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

LTM4605 supports an output voltage range of 0.8V to

16V, set by a resistor. This high efﬁciency design delivers

up to 5A continuous current in boost mode (12A in buck

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

output capacitors are needed to ﬁnish the design.

Single Inductor Architecture Allows V Above,

Below or Equal to V

Phase-Lockable Fixed Frequency: 200kHz to 400kHz

Ultra-Fast Transient Response

Current Foldback Protection

Thelowproﬁlepackageenablesutilizationofunusedspace

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. The LTM4605 can be frequency

synchronized with an external clock to reduce undesirable

frequency harmonics.

Output Overvoltage Protection

Small, Low Proﬁle Surface Mount LGA Package

(15mm × 15mm × 2.8mm)

APPLICATIONS

Telecom, Servers and Networking Equipment

current protection. The DC/DC μModule™ is offered in a

smallandthermallyenhanced15mm×15mm×2.8mmLGA

package. The LTM4605 is Pb-free and RoHS compliant.
