Introduction

AI Translation

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.
