The LT1302CN8-5#PBF is a 5V micropower step-up DC/DC Converter maintains high efficiency over a wide range of output current. It operates from a supply voltage as low as 2V and feature automatic shifting between Burst Mode? operation at light load and current mode operation at heavy load. The internal low loss NPN power switch can handle current in excess of 2A and switch at frequencies up to 400kHz. Quiescent current is just 200μA and can be further reduced to 15μA in shutdown. The LT1302-5 incorporates feedback resistors R1 and R2 into the device. Output voltage is set at 5.05V in Burst Mode?, dropping to 4.97V in current mode. The input supply should be decoupled with a good quality electrolytic capacitor close to the LT1302 to provide a stable input supply.
