ABSTRACT
Multi-stage
power
adapter
techniques
are
described
in
which
a
power
adapter
for
a
device
is
con?gured
to
selectively
switch
between
a
relatively
low
power
supply
and
a
relatively
high
power
supply.
The
low
power
supply
may
be
employed
upon
initial
connection
of
the
adapter
to
a
host
device
to
ensure
that
the
adapter
is
safe
when
disconnected
and
does
not
supply
full
power
before
the
device
is
ready
to
receive
the
highpower
supply.
The
low
power
supply
may
supply
enough
power
for
the
host
device
to
detect
the
connection
of
the
adapter
and
establish
initial
communication
with
the
adapter.
A
switch
to
the
high
power
supply
by
the
adapter
may
then
occur
in
response
to
a
noti?cation
from
the
host
device
that
indicates
the
host
device
is
ready
for
the
high
power
supply.
The
switch
to
high
power
supply
enables
normal
operation
of
the
host
device.
