Description

General part information

LTC3525 Series

The LTC3525D-3.3 is a high efficiency synchronous stepup DC/DC converter that can start up with an input as low as 0.85V. It offers a compact, high efficiency alternative to charge pumps in single cell or dual cell alkaline or Li-Ion applications. Only three small external components are required. The LTC3525D features a fixed output voltage of 3.3V. In shutdown, VOUTis connected to VINthrough the inductor.The device includes a 0.5Ω N-channel MOSFET switch and a 0.8Ω 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 anti-ringing control and thermal shutdown. The LTC3525D is available in a tiny 6-Lead SC70 package.List of LTC3525 OptionsPART NAMEINPUT START-UP VOLTAGEOUTPUT VOLTAGEVOUT STATUS IN SHUTDOWN MODELTC3525-30.85V3VOutput DisconnectLTC3525-3.30.85V3.3VOutput DisconnectLTC3525-50.85V5VOutput DisconnectLTC3525D-3.30.85V3.3VPass Through ModeLTC3525L-30.7V3VOutput DisconnectApplicationsMP3 PlayersPortable InstrumentsGlucose MetersDigital Cameras
