Abstract:
A method for dissipating heat generated on a printed circuit, the printed circuit comprising a supply voltage input, a user with a varying voltage requirement and a voltage-regulating circuit with an output connected to the user for supplying the user with a drive voltage, the drive voltage being regulated through the use of a reference signal which is supplied to the voltage-regulating circuit from the user, said method comprising the step of:connecting a heat dissipating device, comprising at least a resistive part, between the output of the voltage-regulating circuit and the supply voltage input, such that the heat dissipating device is connected in parallel with the voltage-regulating circuit, so that at least a portion of a current supplied to the user passes through the heat dissipating device, wherein the heat dissipating device is external to the printed circuit.
