Datasheet	LTC3526L-2-Linear.pdf

The LTC®3526L-2/LTC3526LB-2 are synchronous, fixed frequency step-up DC/DC converters with output disconnect.

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.
