CONTROL APPARATUS, SWITCHING POWER SUPPLY AND CONTROL METHOD

摘要

Disclosed herein are control apparatus, switching power supply, and control method embodiments for maintaining power conversion efficiency. An embodiment operates by determining whether or not a current of an inductor of the switching power supply has become less than or equal to a predetermined value, controlling a reference voltage based on at least one of a result of the determining or a result of comparing a voltage according to an output voltage of the switching power supply and the reference voltage, and pausing switching of the switching power supply based on the reference voltage.

主权项

1. A control apparatus for a switching power supply, comprising:
a pause controller configured to pause switching of the switching power supply based on a reference voltage; a current determination part configured to determine whether or not a current of an inductor of the switching power supply has become less than or equal to a predetermined value; and a reference voltage controller configured to control the reference voltage based on a result of determining by the current determination part and a result of comparing a voltage according to an output voltage of the switching power supply and the reference voltage.
