UTC LT1304/LT1304-3.3V/LT1304-5.0V  
LINEAR INTEGRATED CIRCUIT  
MICROPOWER DC/DC  
CONVERTERS WITH  
LOW-BATTERY DETECTOR  
ACTIVE IN SHUTDOWN  
DESCRIPTION  
The UTC LT1304 is a micropower step-up DC/DC  
converter ideal for use in small, low voltage,  
battery-operated systems. The devices operate from a  
wide input supply range of 1.5V to 8V.  
SOP-8  
DIP-8  
The UTC LT1304-3.3 and LT1304-5.0 generate  
regulated outputs of 3.3V and 5V and the adjustable  
LT1304 can deliver output voltages up to  
25V.Quiescent current,120 μ A  
in active mode,  
decreases to just 10 μA 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 UTC LT1304 allows the use of small,  
surface-mountable inductors and capacitors.  
FEATURES  
APPLICATIONS  
*5V at 200mA from two cells.  
*2-,3-,or 4-cell to 5V or 3.3V step-up  
*Portable instruments

*Operates with VIN as low as1.5V  
*Low battery detector active in shutdown  
*Low switch VCESAT:370mV at 1A typical.  
*120μA quiescent current in active mode.  
*Bar code scanners  
*Palmtop computers  
*Diagnostic medical instrumentation.  
*Personal data communicators/computers.  
*Switching frequency up to 300kHz  
*Programmable peak current with one resistor.
