LT1304/LT1304-3.3/LT1304-5

Micropower

DC/DC Converters with

Low-Battery Detector

Active in Shutdown

FEATURES

DESCRIPTION

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 I

LIM

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.
