High Efficiency, High Voltage  
50mA Synchronous  
Step-Down Converter  
FEATURES  
DESCRIPTION  
The LTC®3642 is a high efficiency step-down DC/DC  
converter with internal high side and synchronous power  
switches that draws only 12μA typical DC supply current  
at no load while maintaining output voltage regulation.

The LTC3642 can supply up to 50mA load current and  
features a programmable peak current limit that provides  
a simple method for optimizing efficiency in lower current  
applications. The LTC3642’s combination of Burst Mode®  
operation, integrated power switches, low quiescent cur-  
rent, and programmable peak current limit provides high  
efficiency over a broad range of load currents.

With its wide 4.5V to 45V input range and internal  
overvoltagemonitorcapableofprotectingthepartthrough  
60V surges, the LTC3642 is a robust converter suited for  
regulating a wide variety of power sources. Additionally,  
theLTC3642includesapreciserunthresholdandsoft-start  
feature to guarantee that the power system start-up is  
well-controlled in any environment.
