Abstract
A control circuit for a start-up circuit that induces current flow in a bandgap circuit during a start-up phase is disclosed. A comparator passes a power supply to the start-up circuit according to an internal node of the bandgap circuit after the start-up phase. An activating circuit is used to activate the comparator to obtain the power supply at an output earlier than another output node of the comparator.
