DescripTion  
FeaTures  
n
Wide Operating Input Voltage Range: 4.5V to 38V  
The LTM®4641 is a switch mode step-down DC/DC  
µModule® (micromodule) regulator with advanced input  
and load protection features. Trip detection thresholds for  
the following faults are customizable: input undervoltage,  
overtemperature, input overvoltage and output overvolt-  
age. Select fault conditions can be set for latchoff or  
hysteretic restart response—or disabled. Included in the  
packagearetheswitchingcontrollerandhousekeepingICs,  
power MOSFETs, inductor, overvoltage drivers, biasing  
circuitryandsupportingcomponents.Operatingfrominput  
voltages of 4V to 38V (4.5V start-up), the device supports  
output voltages from 0.6V to 6V, set by an external resis-  
tor network remote sensing the point-of-load’s voltage.

SnPb or RoHS Compliant Finish  
The LTM4641’s high efficiency design can deliver up to  
10A continuous current with a few input and output ca-  
pacitors. The regulator’s constant on-time current mode  
control architecture enables high step-down ratios and  
fast response to transient line and load changes. The  
LTM4641 is offered in a 15mm × 15mm × 5.01mm with  
SnPb or RoHS compliant terminal finish.
