FEATURES

DESCRIPTION

The LTM^®4627 is a complete 15A output high efﬁciency

switch mode DC/DC power supply. Included in the pack-

age are the switching controller, power FETs, inductor and

compensationcomponents.Operatingoveraninputvoltage

range from 4.5V to 20V, the LTM4627 supports an output

voltagerangeof0.6Vto5V,setbyasingleexternalresistor.

Only a few input and output capacitors are needed.

Complete 15A Switch Mode Power Supply

Wide Input Voltage Range: 4.5V to 20V

0.6V to 5V Output Range

1.5ꢀ ꢁotal DC Output Error (–40°C to 125°C)

Differential Remote Sense Ampliﬁer for Precision

Regulation

Current Mode Control/ Fast ꢁransient Response

Frequency Synchronization

Current mode operation allows precision current sharing

of up to four LTM4627 regulators to obtain 60A output.

Highswitchingfrequencyandacurrentmodearchitecture

enable a very fast transient response to line and load

changes without sacriﬁcing stability. The device supports

frequency synchronization, multiphase/current sharing

operation, BurstModeoperationandoutputvoltagetrack-

ing for supply rail sequencing.

Parallel Current Sharing (Up to 60A)

Selectable Pulse-Skipping or Burst Mode^®Operation

Soft-Start/Voltage Tracking

Up to 93% Efﬁciency (12V , 3.3V

Overcurrent Foldback Protection

Output Overvoltage Protection

Small Surface Mount Footprint, Low Proﬁle

15mm × 15mm × 4.32mm LGA Package

)

OUT

The LTM4627 is offered in a thermally enhanced 15mm ×

15mm × 4.32mm LGA package. The LTM4627 is PB-free

and RoHS compliant.
