DESCRIPTION  
FEATURES  
Up to 220mA Output Current at 5V from 2V Supply  
Supply Voltage as Low as 1.8V  
Up to 88% Efficiency  
TheLT1300isamicropowerstep-upDC/DCconverterthat  
utilizes Burst Mode™ operation. The device can deliver 5V  
or 3.3V from a two-cell battery input. It features program-  
mable 5V or 3.3V output via a logic-controlled input, no-  
loadquiescentcurrentof120µAandashutdownpinwhich  
reducessupplycurrentto10µA.Theon-chippowerswitch  
has a low 170mV saturation voltage at a switch current of  
1A, a four-fold reduction over prior designs. A 155kHz  
internal oscillator allows the use of extremely small sur-  
facemountinductorsandcapacitors.Operationisguaran-  
teedat1.8Vinput. Thisallowsmoreenergytobeextracted  
from the battery increasing operating life. The ILIM pin can  
be used to program peak switch current with a single  
resistor allowing the use of less expensive and smaller  
inductors and capacitors in lighter load applications. The  
LT1300isavailableinan8-leadSOICpackage, minimizing  
board space requirements. For a 5V/12V Selectable Out-  
put Converter see the LT1301. For increased output cur-  
rent see the LT1302.
