Multiphase DC/DC converter with output phases deviated from or aligned with each other and driven with fixed on time |
摘要 |
A multiphase DC/DC converter according to the present invention includes: a plurality of DC/DC converters whose outputs are connected in common to supply electric power to a load; a load state detection portion which detects a state of the load connected to the plurality of DC/DC converters and outputs a detection result; and a control circuit which drives each of the plurality of DC/DC converters based on outputs from the plurality of DC/DC converters, and based on an output from the load state detection portion, drives the plurality of DC/DC converters with output phases of the plurality of DC/DC converters deviated from each other or with the output phases of the plurality of DC/DC converters aligned with each other. |
