FEATURES  
DESCRIPTION  
TheLTC®3104isahighefficiency,monolithicsynchronous  
step-down converter using a current mode architecture  
capable of supplying 300mA of output current. The  
LTC3104 includes an integrated, adjustable 10mA LDO  
to power noise sensitive functions.

Accurate and Programmable RUN Pin Threshold  
1.2MHz Fixed Frequency PWM  
The LTC3104 offers two operational modes: automatic  
Burst Mode operation and forced continuous mode allow-  
ing the user 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  
2.6µA, maximizing the efficiency for light loads. Selec-  
tion of forced continuous mode provides very low noise  
constant frequency, 1.2MHz operation.

Additionally, the LTC3104 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.
