TYPICAL APPLICATION
DESCRIPTION
The LTC ? 3103 is a high efficiency, monolithic synchronous
step-down converter using a current mode architecture
capable of supplying 300mA of output current.
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.
