Abstract:
1. A semiconductor voltage controller comprising: a start-mode circuit associated with a start-mode; an off-mode circuit associated with an off-mode, where the voltage controller can be configured to receive a feedback signal and an off-mode signal from a single input and provide an output voltage, where the voltage controller can be configured to be in the off-mode when the feedback signal is less than a skip level and the feedback signal is less than an HV-control level, and where the voltage controller can be configured to be in start mode when the feedback signal is greater than the HV-control level and a voltage Vcc is below a voltage Vcc-start; and wherein the voltage controller can be configured: when in the off-mode to start generating a voltage supply signal and a drive signal when the slope of the feedback signal in time is positive and when the feedback signal is equal to about the HV-control level; when in the off-mode to start generating a voltage supply signal when the slope of the feedback signal in time is positive and when the feedback signal is equal to about the HV-control level.
