Method and apparatus to reduce maximum power from a power supply with transition region regulation |
摘要 |
Techniques are disclosed to regulate the output power of a power supply. An example feedback circuit for use in a power supply regulator includes a voltage regulation circuit coupled to sense an output voltage of the power supply regulator. The voltage regulation circuit is coupled to generate a first regulation signal to regulate an output of the power supply regulator if an output current of the power supply is less than a first transition current. A current regulation circuit is coupled to sense an output current of the power supply regulator. The current regulation circuit is coupled to generate a second regulation signal to regulate the output of the power supply regulator if the output voltage of the power supply is less than a second transition voltage. A transition region regulation circuit is coupled to sense the output voltage and the output current of the power supply regulator. The transition region regulation circuit is coupled to generate a third regulation signal to regulate the output of the power supply regulator if the output current of the power supply is between the first transition current and a second transition current. The feedback circuit is coupled to generate a feedback signal output in response to the first, second and third regulation signals. |
