The power factor correction circuit is configured to generate a driving voltage based on the generated direct current voltage. The power factor correction circuit includes a second surge protection circuit and an over-temperature protection circuit. The drive circuit is configured to generate an output voltage for a load based on the driving voltage. The drive circuit includes a third surge protection circuit, a startup circuit, and an open-circuit protection circuit.
