DESCRIPTIO  
FEATURES  
The LT®1308A/LT1308B are micropower, fixed frequency  
step-up DC/DC converters that operate over a 1V to 10V  
input voltage range. They are improved versions of the  
LT1308andarerecommendedforuseinnewdesigns.The  
LT1308A features automatic shifting to power saving  
Burst Mode operation at light loads and consumes just  
140μA at no load. The LT1308B features continuous  
switchingatlightloadsandoperatesataquiescentcurrent  
of 2.5mA. Both devices consume less than 1μA in  
shutdown.

Pin-for-Pin Upgrade Compatible with LT1308  
■
Lower Quiescent Current in Shutdown: 1μA (Max)  
Low-battery detector accuracy is significantly tighter than  
the LT1308. The 200mV reference is specified at ± 2% at  
room and ±3% over temperature. The shutdown pin  
enables the device when it is tied to a 1V or higher source  
and does not need to be tied to VIN as on the LT1308. An  
internal VC clamp results in improved transient response  
and the switch voltage rating has been increased to 36V,  
enabling higher output voltage applications.
