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 compensation components. Operating over an input  
voltage range from 4.5V to 20V, the LTM4627 supports an  
output voltage range of 0.6V to 5V, set by a single external  
resistor.Onlyafewinputandoutputcapacitorsareneeded.

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.
