TYPICAL APPLICATION
DESCRIPTION
3A Low Noise Buck-Boost
DC/DC Converter
The LTC
3113 is a wide VIN range, highly efcient, xed
frequency, buck-boost DC/DC converter that operates
from input voltages above, below or equal to the output
voltage. The topology incorporated in the IC provides low
noise operation, making it well suited for RF and precision
measurement applications.
The LTC3113 can deliver up to 3A of continuous output
current to satisfy the most demanding applications.
Higher output current is possible in stepdown (buck)
mode. Integrated low RDS(ON) power MOSFETs and a
programmable switching frequency up to 2MHz result
in a compact solution footprint. Selectable Burst Mode
operation improves efciency at light loads.
Other features include <1μA shutdown current, integrated
soft-start, short-circuit protection, current limit and ther-
mal overload protection. The LTC3113 is housed in the
thermally enhanced 16-lead (4mm
× 5mm × 0.75mm)
DFN and 20-lead TSSOP packages.
