Switching circuit for use in microprocessor, has programmable memory IC, attached to microprocessor for receiving necessary electricity data signal and program data signal, which is implemented for output of operating voltage control signal

摘要

The circuit has a programmable memory IC attached to a microprocessor for receiving the necessary electricity data signal and the program data signal. The program data signal is implemented for the output of an operating voltage control signal, which is received by a PWM control unit, connected with the programmable memory IC for the output of a PWM signal. A feedback stabilization unit lies between the programmable memory IC and the PWM control unit for seizing an over-voltage, an over-current and a high temperature in the PWM control unit. A control unit is switched between the PWM control unit and a power switch, which receives the PWM signal to make the electricity available for the microprocessor. The voltage supply specification- program- data signal is downloaded from a remote server by an Internet connection. An independent claim is also included for a method for obtaining a voltage supply specification updating of a microprocessor.
