DESCRIPTION  
FEATURES  
The LT®1304 is a micropower step-up DC/DC converter  
ideal for use in small, low voltage, battery-operated sys-  
tems. The devices operate from a wide input supply range  
of 1.5V to 8V. The LT1304-3.3 and LT1304-5 generate  
regulated outputs of 3.3V and 5V and the adjustable  
LT1304 can deliver output voltages up to 25V. Quiescent  
current, 120µA in active mode, decreases to just 10µA in  
shutdown with the low-battery detector still active. Peak  
switch current, internally set at 1A, can be reduced by  
adding a single resistor from the ILIM pin to ground. The  
high speed operation of the LT1304 allows the use of  
small, surface-mountable inductors and capacitors. The  
LT1304 is available in an 8-lead SO package.
