Abstract
A horizontal oscillator, responsive to an on/off control signal, generates an output signal that is coupled via a driver stage to a control terminal of a horizontal deflection output transistor. During a transition interval that follows a standby mode of operation, the duty cycle of the oscillator output signal is reduced relative to when a run mode of operation occurs to provide soft-start operation.
