LTC3630  
High Efficiency, 65V  
500mA Synchronous  
Step-Down Converter  
FEATURES  
DESCRIPTION  
The LTC®3630 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  
while maintaining a regulated output voltage at no load.

No Compensation Required  
n
Adjustable 50mA to 500mA Maximum Output Current  
The LTC3630 can supply up to 500mA 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 LTC3630’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.

Low Profile (0.75mm) 3mm × 5mm DFN and  
Thermally-Enhanced MSE16 Packages  
With its wide input range of 4V to 65V, the LTC3630 is a  
robust converter suited for regulating a wide variety of  
powersources.Additionally,theLTC3630includesaprecise  
run threshold and soft-start feature to guarantee that the  
power system start-up is well-controlled in any environ-  
ment. A feedback comparator output enables multiple  
LTC3630s to be paralleled in higher current applications.
