Title:
ELECTRONIC SYSTEM, ELECTRONIC DEVICE AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/029659
Kind Code:
A1
Abstract:
Provided is an electronic system wherein power is accurately supplied even with
a power source supply line resistance and a connector contact resistance, and
furthermore, a plurality of electronic devices having requiring different
power supply voltages can be handled with one power supply device. The electronic
system is provided with an electronic device (50), and a power supply device (10)
which is arranged to be connected/removed to and from the electronic device (50)
and supplies power through a cable when connected. The electronic device (50)
is provided with a first detection circuit (51) for performing detection relating
to the supply quantity of the power supply and outputting a first detection signal,
and a control signal terminal (T2) for transmitting the first detection signal
to the power supply device (10) when connected to the power supply device. The
power supply device (10) is provided with an output variable power supply circuit
(11), and a control circuit (12) for controlling the output from the power supply
circuit (11) based on the first detection signal.
