Analog Devices (ADI) is a world leader in the design, manufacture, and marketing of a broad portfolio of high performance analog, mixed-signal, and digital signal processing (DSP) integrated circuits (ICs) used in virtually all types of electronic equipment. Since our inception in 1965, we have focused on solving the engineering challenges associated with signal processing in electronic equipment. Used by over 100,000 customers worldwide, our signal processing products play a fundamental role in converting, conditioning, and processing real-world phenomena such as temperature, pressure, sound, light, speed, and motion into electrical signals to be used in a wide array of electronic devices.
Description:
The LTC®3526-2/LTC3526B-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 an 850mV start-up voltage and operation down to 500mV once started. A switching frequency of 2MHz 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 LTC3526-2 featuresBurstMode operation atlightload conditions, while the LTC3526B-2 features continuous switching. Anti-ring circuitry eliminates EMI concerns by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1µA and thermal shutdown. The LTC3526-2/LTC3526B-2 are housed in a 6-pin 2mm × 2mm × 0.75mm DFN package. For new designs, we recommend the LTC3526L-2/ LTC3526LB-2.
