ARRANGEMENT COMPRISING A MICROPROCESSOR, A DEMAGNETIZATION CIRCUIT AND A SWITCHED MODE POWER SUPPLY, AND A DISPLAY UNIT COMPRISING A RESPECTIVE ARRANGEMENT.

摘要

The arrangement and the respective display unit comprise a microprocessor (16), a demagnetization circuit and a switched mode power supply operating in a normal mode and in a low power mode. The microprocessor (16) is coupled via the same output (19) to the switched mode power supply for controlling the low power mode and to the demagnetization circuit for controlling a respective operation. The output of the microprocessor is in particular arranged as a single pin. In a preferred embodiment, the control signal (Uc) from the microprocessor (16) provides a control for a low power burst mode, and is further combined with a power on-indicative signal (U4) via a logical AND combination (23) for controlling the demagnetization circuit.
