<p>The circuit has a driver (206) with an output (G) connected with a control output of a primary-sided circuit. The circuit is so arranged that it adjusts a switching frequency of the primary-sided circuit depending on an auxiliary voltage. A constant factor of the voltage is so chosen that an output current of a switching power supply receives a preset value. The output is connected with an input of a comparator (205) by the circuit. An independent claim is also included for a method of controlling an output voltage of a primary-controlled switching power supply.</p> |
