TYPICAL APPLICATION
DESCRIPTION
Dual Channel 550mA 1MHz
Synchronous Step-Up
DC/DC Converter
The LTC3535 is a dual channel, synchronous, xed fre-
quency step-up DC/DC converter with output disconnect.
Extended battery life in single AA/AAA powered products
is realized with a 680mV start-up voltage and operation
down to 500mV once started.
A switching frequency of 1MHz minimizes solution foot-
print by allowing the use of tiny, low prole inductors
and ceramic capacitors. The current mode PWM design
is internally compensated, reducing external parts count.
The LTC3535 features Burst Mode operation at light load
conditions allowing it to maintain high efciency over a
wide range of load. Anti-ring circuitry reduces EMI by
damping the inductor in discontinuous mode. Additional
features include a low shutdown current of under 1μA and
thermal shutdown.
The LTC3535 is housed in a 3mm
× 3mm × 0.75mm
DFN package.
