DESCRIPTION  
FEATURES  
The LT®1307/LT1307B are micropower, fixed frequency  
DC/DC converters that operate from an input voltage as  
low as 1V. First in the industry to achieve true current  
mode PWM performance from a single cell supply, the  
LT1307 features automatic shifting to power saving Burst  
Mode operation at light loads. High efficiency is main-  
tained over a broad 100µA to 100mA load range. The  
LT1307B does not shift into Burst Mode operation at light  
loads, eliminating low frequency output ripple at the  
expenseoflightloadefficiency. Thedevices containalow-  
battery detector with a 200mV reference and shut down to  
less than 5µA. No load quiescent current of the LT1307 is  
50µAandtheinternalNPNpowerswitchhandles a500mA  
current with a voltage drop of just 295mV.

U
Unlike competitive devices, large electrolytic capacitors  
are not required with the LT1307/LT1307B in single cell  
applications. The high frequency (600kHz) switching al-  
lows the use of tiny surface mount multilayer ceramic  
(MLC) capacitors along with small surface mount induc-  
tors. The devices work with just 10µF of output capaci-  
tance and require only 1µF of input bypassing.
