Description

General part information

LTC3528 Series

The LTC3528B-2 is a synchronous, ﬁxed frequency step-up DC/DC converter with output disconnect. High efficiency synchronous rectification, in addition to a 700mV start-up voltage and operation down to 500mV once started, provides longer run-time for single or multiple cell battery-powered products.A switching frequency of 2MHz minimizes solution foot- print by allowing the use of tiny, low proﬁle inductors and ceramic capacitors. The current mode PWM is internally compensated, simplifying the design process. The LTC3528B-2 features continuous switching at light loads. Anti-ringing circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current, open-drain power good output, short- circuit protection and thermal overload protection.The LTC3528B-2 is offered in an 8-lead 2mm × 3mm × 0.75mm DFN package.FrequencyFeaturesLTC35281MHzYesLTC3528B1MHzNoLTC3528-22MHzYesLTC3528B-22MHzNoApplicationsMedical InstrumentsFlash-Based MP3 PlayersNoise Canceling HeadphonesWireless MiceBluetooth Headsets
