35262b2f
500mA 2MHz Synchronous
Step-Up DC/DC Converters
in 2mm × 2mm DFN
The LTC
3526-2/LTC3526B-2 are synchronous, xed
frequency step-up DC/DC converters with output discon-
nect. Synchronous rectication enables high efciency
in the low prole 2mm × 2mm DFN package. Battery life
in single AA/AAA powered products is extended further
with an 850mV 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 prole inductors
and ceramic capacitors. The current mode PWM design
is internally compensated, reducing external parts count.
The LTC3526-2 features Burst Mode operation at light load
conditions, while the LTC3526B-2 features continuous
switching. Anti-ring circuitry eliminates EMI concerns by
damping the inductor in discontinuous mode. Additional
features include a low shutdown current of under 1A and
thermal shutdown.
The LTC3526-2/LTC3526B-2 are housed in a 6-pin
2mm × 2mm × 0.75mm DFN package.
