DescripTion  
TheLTC®3526/LTC3526Baresynchronous,fixedfrequency  
step-up DC/DC converters with output disconnect. Syn-  
chronous rectification enables high efficiency in the low  
profile 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.

Operation  
IN

A switching frequency of 1MHz minimizes solution foot-  
print by allowing the use of tiny, low profile 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-  
tinuousmode. Additionalfeaturesincludealowshutdown  
current of under 1µA and thermal shutdown.
