A POWER CIRCUIT OF AN ELECTRONIC DEVICE WHICH CAN REDUCE POWER CONSUMPTION. POWER IS SAVED BY TURNING OFF THE VOLTAGE BOOSTER (320) IN THE POWER -SAVING MODE. A CONTROLEER (IC3) IS USED TO GENERATE A CONTROL SIGNAL INDICATING WHETHER OR NOT THE ELECTRONIC DEVICE (28) IS IN A POWER-SAVING MODE. A SWITCH (330/340), COUPLE BETWEEN THE VOLTAGE BOOSTER (320) AND ITS POWER SUPPLY, IS USED FOR DISCONNECTING THE POWER SUPPLY FROM THE VOLTAGE BOOSTER (320) WHEN THE CONTROL SIGNAL INDICATES THAT THE ELECTRONIC DEVICE (28) IS IN THE POWER-SAVING MODE.(FIG. 3)
