Description
Demonstration circuit 2041A is a switched-capacitor
step-down power supply featuring the
LTC
®
3255.
The
LTC3255 has the ability to step down voltage 2:1 to ef-
ficiently regulate output voltages less than half the V
IN
voltage reducing the input current needed. As V
IN
reduces
below twice V
OUT
, the LTC3255 will automatically switch
to 1:1 mode.
The LTC3255 also has an integrated shunt regulator al-
lowing it to provide a regulated output from a 4mA to
20mA current loop.
The LTC3255 is a robust device that can survive reverse-
polarity input supplies with current limit and overtem-
perature protection.
Refer to the LTC3255 data sheet for more details on the
electrical and timing specifications.
