ABSTRACT:
A lamp driver circuit is disclosed. The lamp driver circuit comprises a passive power factor correction (PFC) circuit. The passive PFC circuit, in operation, is coupled with an alternating-current (AC) power source. The lamp driver circuit further includes a direct-current to direct-current (DC-DC) power converter coupled with the passive PFC circuit. The DC-DC power converter, in conjunction with the passive PFC circuit, operates as a constant energy converter. The lamp driver circuit also includes a lamp circuit coupled with the DC-DC power converter.
