Primary feedback switching power converter controller with intelligent determination of and response to output voltage drops due to dynamic load conditions

摘要

The embodiments herein include a primary-side controller for a switching power converter that is capable of receiving a detection signal from a secondary-side detection circuit indicating that an output voltage has reached a condition. The controller determines the appropriate action once a detection signal has been received by distinguishing whether a dynamic load condition has been placed on the power supply versus other operating conditions.
