TYPICAL APPLICATION
DESCRIPTION
The LX13097 is a current mode PWM buck switcher
with internal compensation, can provide up to 1A output
current with FET on board. It operates from 2.8V to 5.5V
and output as low as 0.6V which is ideal for the applica-
tion with single cell Li-Ion battery as well as other 3.3V
input bus supply applications. Switching frequency is
fixed 1MHz, small surface mount inductors and capaci-
tors are allowed to use, make it good for portable appli-
cations.
LX13097 is available in 5-pin SOT23 package.
