DESCRIPTION
The LT
®
1303/LT1303-5 are micropower step-up high
efficiency DC/DC converters using Burst Mode
TM
opera-
tion. They are ideal for use in small, low-voltage battery-
operated systems. The LT1303-5 accepts an input voltage
between 1.8V and 5V and converts it to a regulated 5V. The
LT1303 is an adjustable version that can supply an output
voltage up to 25V. Quiescent current is only 120µA from
the battery and the shutdown pin further reduces current
to 10µA. The low-battery detector provides an open-
collector output that goes low when the input voltage
drops below a preset level. The on-chip NPN power switch
has a low 170mV saturation voltage at a switch current
of 1A. The LT1303/LT1303-5 are available in 8-lead PDIP
or SO packages, easing board space requirements.
For higher output current, please see the LT1305 or
LT1302.
