摘要： The present invention relates to a multiple-output voltage converter. A basic idea of the present invention is to provide a multiple-output converter which may be adapted to various output power conditions. The converter has, in an exemplifying embodiment, three outputs which all share a common tapped inductor (301, 302). An inductor tap is employed to control the inductance of the inductor. A large inductance is used for low power standby operation and a small inductance is used when, for example, the LED backlight is switched on. Switches are arranged at the converter outputs to select to which one of the respective converter outputs the energy of the inductor is to be transferred.
