The LTC3539/LTC3539-2 are synchronous, 2A step-up DC/DC converters with output disconnect. Synchronous rectification enables high efficiency in the low profile 2mm × 3mm DFN package. Battery life is extended with a 700mV start-up voltage and operation down to 500mV once started.

A switching frequency of 1MHz (LTC3539) or 2MHz (LTC3539-2) minimizes solution footprint 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 LTC3539/LTC3539-2 feature a pin-enabled automatic Burst Mode operation at light load conditions. Anti-ring circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1μA and thermal overload protection.

The LTC3539/LTC3539-2 are offered in a 2mm × 3mm × 0.75mm DFN package.

Product Detail

Demonstration circuits 1260A-A and 1260A-B are high-efficiency synchronous boost converters capable of operating with an input voltage range from 0.7V to 5.5V using the LTC3539 and LTC3539-2 respectively. The 2 × 3 mm DFN thermally enhanced package with a 1MHz switching frequency (2MHz for the -2 part) and the 2A internal switches provide a very tiny overall solution.


Jumpers are provided for selecting 1.8V, 3.3V or 5V at the output and the circuit can provide 300mA at 3.3V from a 1.5V input and can provide up to 900mA depending on the input and output voltage used.
