DESCRIPTIO  
FEATURES  
The LTM®4600HV is a complete 10A, DC/DC step down  
power supply with up to 28V input operation. Included  
in the package are the switching controller, power FETs,  
inductor, and all support components. Operating over  
an input voltage range of 4.5V to 28V, the LTM4600HV  
supports an output voltage range of 0.6V to 5V, set by a  
single resistor. This high efficiency design delivers 10A  
continuous current (12A peak), needing no heat sinks or  
airflow to meet power specifications. Only bulk input and  
output capacitors are needed to finish the design.  
Complete Switch Mode Power Supply  
Wide Input Voltage Range: 4.5V to 28V  
10A DC, 12A Peak Output Current

(LTM4600HVMPV)  
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.

The LTM4600HV is packaged in a thermally enhanced,  
compact (15mm × 15mm) and low profile (2.8mm) over-  
molded Land Grid Array (LGA) package suitable for auto-  
mated assembly by standard surface mount equipment.  
The LTM4600HV is Pb-free and RoHS compliant.
