Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The LTC3535 is guaranteed to meet performance specifi cations from 0 to 85. Specifi cations over the 40 to 85 operating temperature range are assured by design, characterization and correlation with statistical process controls.
Note 5: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 125 when overtemperature protection is active.Continuous operation above the specifi ed maximum operating junction temperature may result in device degradation or failure.

The LTC®3535 is a dual channel, synchronous, fi xed frequency step-up DC/DC converter with output disconnect. Extended battery life in single AA/AAA powered products is realized with a 680mV start-up voltage and operation down to 500mV once started.

A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profi le inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count.The LTC3535 features Burst Mode operation at light load conditions allowing it to maintain high effi ciency over a wide range of load. Anti-ring circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1A and thermal shutdown.

The LTC3535 is housed in a 3mm * 3mm * 0.75mm DFN package.
