DESCRIPTION  
TheLTM®4600isacomplete10A,DC/DCstepdownpower  
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  
LTM4600 supports an output voltage range of 0.6V to 5V,  
setbyasingleresistor. Thishighefficiency design delivers  
10Acontinuouscurrent(14Apeak), needingnoheatsinks  
or airflow to meet power specifications. Only bulk input  
and output capacitors are needed to finish the design.

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