Technical Examples
  1. A switching power supply unit, for switching a rectified voltage supplied to a pulse transformer to supply a specified load voltage to a load connected to the secondary winding of the pulse transformer, wherein at the time of normal operation, a rectified voltage is supplied via a first resistor to a power supply terminal of a control circuit, together with supply of a voltage generated at a drive winding of the pulse transformer to the power supply terminal via a diode, and at the time of standby operation, a standby signal from outside indicating that the switching power supply unit has been put into standby mode is received, and it is possible to completely cut-off supply of power to a control section of the switching power supply unit constituting a main power supply when in standby mode, by supplying a voltage that is lower than a power supply threshold voltage capable of operating a control circuit to the power supply terminal.
