General Description
SY7200A
is
DC/DC
step-up
converter
that
deliver
an
accurate
constant
current
for driving
LEDs.
Operation
at
a
fixed
switching
frequency
of
1MHz
allows
the
device
to
be
used
with
small
value
external
ceramic
capacitors
and inductor.
LEDs
connected
in series
are
driven
with
a
regulated
current
set
by
the
external
resistor. The SY7200A is ideal for driving up to eight
white LEDs in series or up to 30V.
