The LT1317B are micropower, fixed frequency step-up DC/DC converters that operate over a wide input voltage range of 1.5V to 12V. 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 LT1317B contain an internal low-battery detector with a 200mV reference that stays alive when the device goes into shutdown.
The internal NPN power switch handles a 500mA current with a voltage drop of just 300mV.
The LT1317B are available in MS8 and SO-8 packages.
