LT1302- 5 General Description
The LT®1302/LT1302-5 are micropower step-up DC/DCconverters that maintain high efficiency over a widerange of output current. They operate from a supplyvoltage as low as 2V and feature automatic shiftingbetween Burst Mode operation at light load, and currentmode operation at heavy load.
The internal low loss NPN power switch can handlecurrent in excess of 2A and switch at frequencies up to400kHz. Quiescent current is just 200µA and can befurther reduced to 15µA in shutdown.
Available in 8-pin PDIP or 8-pin SO packaging, the LT1302/LT1302-5 have the highest switch current rating of anysimilarly packaged switching regulators presently on themarket.
