FEATURES  
DESCRIPTION  
TheLTC®3103isahighefficiency,monolithicsynchronous  
step-down converter using a current mode architecture  
capable of supplying 300mA of output current.

OUT  
The LTC3103 offers two operational modes: automatic  
Burst Mode operation and forced continuous mode allow-  
ing the user the ability to optimize output voltage ripple,  
noise and light load efficiency. With Burst Mode operation  
enabled, the typical DC input supply current at no load  
drops to 1.8µA maximizing the efficiency for light loads.  
Selection of forced continuous mode provides very low  
noise constant frequency, 1.2MHz operation.

Additionally, the LTC3103 includes an accurate RUN com-  
parator, thermal overload protection, a power good output  
and an integrated soft-start feature to guarantee that the  
power system start-up is well controlled.
