Description
General part information
LTC3527 Series
The LTC3527/LTC3527-1 are dual high efficiency, step-up DC/DC converters in a space saving 16-lead 3mm × 3mm QFN package. Battery life is maximized with a 700mV startup voltage and operation down to 500mV once started. TheSHDNand PGOOD pins enable the converters to be sequenced or started together.The LTC3527/LTC3527-1 limit inrush current during startup. Selectable 1.2MHz or 2.2MHz operation provides a choice between the highest efficiency or smallest solution footprint. The current mode PWM design is internally compensated reducing external parts count. Burst Mode operation or fixed frequency operation is selectable via the MODE pin. Anti-ring circuitry reduces EMI in discontinuous mode. This device also features thermal shutdown.True output disconnect allows the output to be completely open in shutdown. The LTC3527-1 actively discharges VOUT1or VOUT2when its respectiveSHDNgoes low. Quiescent current in shutdown is less than 2μA.ApplicationsMP3/Personal Media PlayersNoise Canceling/Bluetooth HeadsetsWireless MicePortable Medical Instruments
