ANALOG DEVICES LT1317CMS8#PBF Switching Regulator, Boost, 600kHz, 1.5V to 12V Input, 30V Output, 800mA, Adjustable, MSOP-8

LT1317CMS8#PBF is a micropower, fixed-frequency step-up DC/DC converter that operates 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, resulting in low output ripple voltage, even at high input voltages. It contains an internal low-battery detector with a 200mV reference that stays alive when the device goes into shutdown. Applications include cellular telephones, cordless telephones, pagers, GPS receivers, battery backup, portable electronic equipment, glucose meters, and diagnostic medical instrumentation.
