<p>PROBLEM TO BE SOLVED: To stabilize timing for on-off switching that outputs an output voltage of a pair of DC-DC converters for outputting output voltages different from each other.SOLUTION: The driving circuit and method for a plurality of DC-DC converters use a converter (26) for a first DC-DC converter driver (2) and a photo coupler (10) for a second DC-DC converter driver (3), respectively, and is configured to feed back a first secondary voltage (14) that is an output of the first DC-DC converter driver (2) to a second input side (4B) of the second DC-DC converter driver (3) after the first DC-DC converter driver (2) is started up.</p> |
