Introduction

AI Translation

The LTC3526L/LTC3526LB 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.

A switching frequency of 1MHz 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 LTC3526L features Burst Mode operation at light load conditions allowing it to maintain high efficiency over a wide range of load. The LTC3526LB features fixed frequency operation for low noise applications. Anti-ring circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1µA and thermal shutdown.

The LTC3526L/LTC3526LB are housed in a 2mm × 2mm × 0.75mm DFN package.
