Description

General part information

LT1317 Series

The LT1317/LT1317B are micropower, fixed frequency step-up DC/DC converters that operate over a wide input voltage range of 1.5V to 12V. The LT1317 features automatic shifting to power saving Burst Mode™operation at light loads. High efficiency is maintained over a broad 300µA to 200mA load range. Peak switch current during Burst Mode operation is kept below 250mA for most operating conditions which results in low output ripple voltage, even at high input voltages. The LT1317B does not shift into Burst Mode operation at light loads, eliminating low frequency output ripple at the expense of light load efficiency.The LT1317/LT1317B contain an internal low-battery detector with a 200mV reference that stays alive when the device goes into shutdown.No-load quiescent current of the LT1317 is 100µA and shuts down to 30µA. The internal NPN power switch handles a 500mA current with a voltage drop of just 300mV.The LT1317/LT1317B are available in MS8 and SO-8 packages.ApplicationsCellular TelephonesCordless TelephonesPagersGPS ReceiversBattery BackupPortable Electronic EquipmentGlucose MetersDiagnostic Medical Instrumentation
