Abstract

A secondary control circuit includes a voltage regulator circuit to be coupled to an output of a power converter to provide a regulated power supply. One or more switched loads is coupled between a first terminal to be coupled to the output of the power converter and an output ground terminal. One or more comparator circuits is coupled to a second terminal coupled to receive an output sense signal. Each one of the one or more comparator circuits is coupled to receive a respective one of one or more reference signals. Each respective one of the one or more reference signals is a scaled representation of a first one of the one or more reference signals. Each one of the one or more switched loads is coupled to be switched in response to an output of a respective one of the one or more comparator circuits.

First claim

What is claimed is:

1. A secondary control circuit for use in a power converter, comprising:
a voltage regulator circuit to be coupled to an output of the power converter coupled to provide power to an output load coupled to the output of the power converter, the voltage regulator circuit coupled to provide a regulated power supply of the secondary control circuit;
one or more switched loads coupled between a first terminal and an output ground terminal of the power converter, w…
