Indication control circuit for indicating workload of electronic device
A workload indicating control circuit includes a coupling circuit, a square wave signal producing circuit, and an integral circuit. The coupling circuit induces a current output by a power input circuit of an electronic device and produces a proportional induced voltage, the current output by the power input circuit being proportional to the workload of the electronic device. The square wave signal producing circuit converts the induced voltage from the coupling circuit into a square wave voltage with corresponding amplitude. The integral circuit takes the square wave signal and modulates the square wave voltage into a sawtooth voltage, to drive the light-emitting unit to emit light according to the sawtooth voltage.
