500mA 1MHz Synchronous
Step-Up DC/DC Converters
in 2mm × 2mm DFN
TheLTC3526/LTC3526Baresynchronous,xedfrequency
step-up DC/DC converters with output disconnect. Syn-
chronous 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 1MHz minimizes solution foot-
print by allowing the use of tiny, low prole inductors and
ceramic capacitors. The current mode PWM design is
internallycompensated,reducingexternalpartscount.The
LTC3526 features automatic Burst Mode operation at light
load conditions, while the LTC3526B features continuous
switching at light loads. Anti-ringing control circuitry also
reduces EMI concerns by damping the inductor in discon-
tinuous mode. Additional features include a low shutdown
current of under 1A and thermal shutdown.
The LTC3526/LTC3526B are housed in a 2mm × 2mm ×
0.75mm DFN package.
