System and Method for a Power Supply Controller

摘要

In accordance with an embodiment, a power supply controller includes an error signal input configured to be coupled to a sensing node of a power supply, a control output configured to be coupled to a switch control circuit, and a control circuit having an input coupled to the error signal input. The control circuit is configured to provide a first variable limit signal if the error signal input is in a first range, and to adjust the first variable limit signal according to the error signal input.
