Description
General part information
LTC3525L-3 Series
The LTC3525L-3 is a high efficiency synchronous step-up DC/DC converter with output disconnect that can start up with an input as low as 0.7V. It offers a compact, high efficiency alternative to charge pumps in single cell or dual cell alkaline applications. Only three small external components are required. The LTC3525L-3 generates a fixed 3V output voltage.The device includes a 0.5Ω N-channel MOSFET switch and a 0.85Ω P-channel synchronous rectifier. Peak switch current ranges from 150mA to 400mA, depending on load, providing enhanced efficiency. Quiescent current is an ultralow 7μA, maximizing battery life in portable applications.Other features include <1μA shutdown current, anti-ringing control and thermal shutdown. The LTC3525L-3 is available in a tiny 6-pin SC70 package.VoutMin Startup VoltageFeaturesLTC3525-3/3.3/53V/3.3V/5V1VOutput DisconnectLTC3525D-3.33.3V0.85VPass Through ModeLTC3525L-33V0.85VOutput DisconnectApplicationsMP3 PlayersPortable InstrumentsGlucose MetersDigital Cameras
