LTC3639  
High Efficiency, 150V  
100mA Synchronous  
Step-Down Regulator  
FeaTures  
DescripTion  
The LTC®3639 is a high efficiency step-down DC/DC  
regulator with internal high side and synchronous power  
switches that draws only 12μA typical DC supply current  
while maintaining a regulated output voltage at no load.

Adjustable 10mA to 100mA Maximum Output  
The LTC3639 can supply up to 100mA load current and  
features a programmable peak current limit that provides  
a simple method for optimizing efficiency and for reduc-  
ing output ripple and component size. The LTC3639’s  
combination of Burst Mode® operation, integrated power  
switches, low quiescent current, and programmable peak  
current limit provides high efficiency over a broad range  
of load currents.

Programmable Input Overvoltage Lockout  
Thermally Enhanced High Voltage MSOP Package  
Withitswideinputrangeof4Vto150Vandprogrammable  
overvoltage lockout, the LTC3639 is a robust regulator  
suitedforregulatingfromawidevarietyofpowersources.  
Additionally, theLTC3639includesaprecise runthreshold  
and soft-start feature to guarantee that the power system  
start-up is well-controlled in any environment. A feedback  
comparator output enables multiple LTC3639s to be con-  
nected in parallel for higher current applications.
