Description

General part information

LTC3526 Series

The LTC3526/LTC3526B 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 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 LTC3526 features automatic Burst Mode operation at light load conditions, while the LTC3526B features continuous switching at light loads. Anti-ringing control circuitry also reduces EMI concerns by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1μA and thermal shutdown.The LTC3526/LTC3526B are housed in a 2mm × 2mm × 0.75mm DFN package.For new designs, we recommend the LTC3526L/LTC3526LB.Startup VoltageFrequencyBurst ModeNotesLTC35261V1MHzYesNot Recommended For New DesignsLTC3526B1V1MHzNoNot Recommended For New DesignsLTC3526-21V2MHzYesNot Recommended For New DesignsLTC3526B-21V2MHzNoNot Recommended For New DesignsLTC3526L0.85V1MHzYesLTC3526LB0.85V1MHzNoLTC3526L-20.85V2MHzYesLTC3526LB-20.85V2MHzNoAPPLICATIONSMedical InstrumentsFlash-Based MP3 PlayersNoise Canceling HeadphonesWireless MiceBluetooth Headsets
