Abstract
A base voltage of a regulator transistor is developed during normal operation in a filter capacitor coupled to a flyback transformer of a horizontal deflection circuit. After a transition to a standby mode of operation, the deflection circuit is disabled and the capacitor begins discharging. The emitter of the transistor is coupled to a load circuit. A supply voltage is coupled to the collector of the transistor during both standby and normal mode. To reduce the loading of a standby power supply that generates the collector voltage as along as the capacitor is not fully discharged, an active turnoff of the regulator transistor is provided immediately after the receiver goes into the standby mode of operation so as to actively turnoff the current drawn by the transistor.
