550mA 2MHz Synchronous
Step-Up DC/DC Converters
in 2mm
× 2mm DFN
The LTC3526L-2/LTC3526LB-2 are synchronous, fixed
frequency step-up DC/DC converters with output discon-
nect. Synchronous rectification enables high efficiency in
the low profile 2mm
× 2mm DFN package. Battery life in
single AA/AAA powered products is extended further with
a 680mV start-up voltage and operation down to 500mV
once started.
A switching frequency of 2MHz minimizes solution foot-
print by allowing the use of tiny, low profile inductors
and ceramic capacitors. The current mode PWM design
is internally compensated, reducing external parts count.
The LTC3526L-2 features Burst Mode operation at light
load conditions allowing it to maintain high efficiency over
a wide range of load. The LTC3526LB-2 features fixed
frequency operation for low noise applications. Anti-ring
circuitry reduces EMI by damping the inductor in discon-
tinuous mode. Additional features include a low shutdown
current of under 1A and thermal shutdown.
The LTC3526L-2/LTC3526LB-2 are housed in a 2mm
×
2mm
× 0.75mm DFN package.
