A novel timing circuit with a long preheating/ignition interval which is used in ballast ICs is presented. It consists of a control unit and a delay unit, both of which are compact and simple. The prime advantage of the proposed circuit is its function of long preheating time which is longer than 0.5s. The circuit is a replacement of an off-chip preheating/ignition circuit, therefore reducing number of the components used in the ballast external circuits.
