Claim:
1. An electronic apparatus mounted with a power delivery device, the power delivery device comprising: an AC/DC converter connected to an AC input terminal, the AC/DC converter configured to change an AC input voltage to a first desired voltage value to be output from a first output terminal in accordance with a first voltage changing control signal, the first voltage changing control signal output from a primary-side controller; a DC/DC converter connected the first output terminal of the AC/DC converter, the DC/DC converter configured to change the output from the AC/DC converter to a second desired voltage value to be output as a DC output voltage from a DC output voltage terminal in accordance with a second voltage changing control signal; capacitors each having a first end and a second end, the first ends of the capacitors being connected to the DC output voltage terminal; secondary-side controllers respectively connected to the second ends of the capacitors, the secondary-side controllers capable of controlling the DC output voltage; a control DC/DC converter connected to the secondary-side controllers, the control DC/DC converter connected to transistors disposed in the DC/DC converter, the control DC/DC converter capable of constantly holding the DC output voltage by controlling the transistors; and a connection line having a first end connected to the control DC/DC converter and a second end connected to the primary-side controller, the connection line being used for bidirectionally transmitting a synchronous signal to the control DC/DC converter and the primary-side controller, wherein the AC/DC converter and the DC/DC converter are interlocked with each other to change the DC output voltage to a desired target voltage.
