FEATURES

DESCRIPTION

The LTM^®4609 is a high efficiency switching mode buck-

boost power supply. Included in the package are the

switching controller, power FETs and support compo-

nents. 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 efficiency 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 finish the design.

Single Inductor Architecture Allows V Above,

Below or Equal to V

Current Mode Control

Power Good Output Signal

Phase-Lockable Fixed Frequency: 200kHz to 400kHz

Ultrafast Transient Response

Current Foldback Protection

Output Overvoltage Protection

Small Surface Mount Footprint, Low Profile

(15mm × 15mm × 2.82mm) LGA and

(15mm × 15mm × 3.42mm) BGA Packages

SnPb (BGA) or RoHS Compliant (LGA and BGA) Finish

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

LTM4609 can be frequency synchronized with an external

clock to reduce undesirable frequency harmonics.

Fault protection features include overvoltage and fold-

back current protection. The DC/DC µModule^®regulator is

offered in small 15mm × 15mm × 2.82mm LGA and 15mm

× 15mm × 3.42mm BGA packages. The LTM4609 is avail-

able with SnPb (BGA) or RoHS compliant terminal finish.
