Description

The LT1305 is a micropower step-up DC/DC converter that uses Burst Mode™operation. Similar to the LT1303, the LT1305 features a 2A internal low-loss switch and can deliver up to four times the output power of the LT1303.Quiescent current is only 120µA and the Shutdown pin further reduces current to 10µA. A low-battery detector provides an open-collector output that goes low when the input voltage drops below a preset level. The LT1305 is available in an 8-pin SO, easing board space requirements.Applications2-Cell and 3-Cell to 5V ConversionEL Panel DriversPortable Instruments
