Abstract
A system and method is providing for adjusting the current limit of a power supply. The current limit is set at a level that corresponds to the maximum flow of amperage that is within the bounds of the power characteristics of the input line to the power supply.
Claims20
A method for adjusting the current limit in a power supply, comprising the step of:
- identifying the voltage level of the input line to the power supply;
- and
- setting a current limit at the output of the power supply;
- wherein the current limit at the output of the power supply is set in relation to the voltage level of the input line to the power supply such that the current limit is set at a lower level when the voltage level of the input line is at a lower level.

A system for adjusting the current limit of a power supply in relation to the voltage characteristics of an input line, comprising:
- a voltage identification module coupled to the input line, the peak detection unit providing an output signal representative of the voltage level of the input line;
- and
- a current limit module that receives the output signal of the voltage identification module as an input and provides as an output a current limit signal that has a value that is related to the voltage characteristics of the input line.
A method for adjusting the current limit of a power supply, comprising the steps of:
- identifying the voltage level of the input line to the power supply;
- and
- establishing a current limit signal in relation to a maximum current limit associated with the voltage level of the input line.
