TYPICAL APPLICATION
FEATURES
DESCRIPTION
1A Low Noise, Buck-Boost
DC/DC Converter
The LTC3536 is an extended VIN range, fixed frequency,
synchronous buck-boost DC/DC converter that operates
from input voltages above, below or equal to the regulated
output voltage. The topology incorporated in the LTC3536
provides low noise operation, making it ideal for RF and
precision measurement applications.
The device can produce up to 1A of continuous output
current, and it includes two N-channel and two P-channel
MOSFET switches. Switching frequencies up to 2MHz can
be programmed with an external resistor and the oscilla-
tor can be synchronized to an external clock. Quiescent
current is only 32A in Burst Mode operation, maximizing
battery life in portable applications. Burst Mode operation
is user controlled and improves efficiency at light loads.
Other features include a 1A shutdown current, internal
soft-start, overtemperature protection and current limit.
The LTC3536 is available in 12-pin thermally enhanced
MSOP and 10-pin (3mm
× 3mm) DFN packages.
