LT1317/LT1317B Micropower, 600kHz PWM DC/DC Converters FEATURES s s s s s s DESCRIPTION The LT ®1317/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 ModeTM 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 loa...
