DESCRIPTIO  
FEATURES  
The LTM®4602HV is a complete 6A, 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 LTM4602HV  
supports an output voltage range of 0.6V to 5V, set by  
a single resistor. This high efficiency design delivers 6A  
continuous current (8A 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  
6A DC, Typical 8A Peak Output Current  
0.6V to 5V Output Voltage  
1.5% Output Voltage Regulation  
Ultrafast Transient Response  
Parallel µModule™ DC/DC Converters  
Current Mode Control  
Pin Compatible with the LTM4600 and LTM4602  
Up to 92% Efficiency  
Programmable Soft-Start  
Output Overvoltage Protection  
Optional Short-Circuit Shutdown Timer  
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.
