Abstract (en)

A discharge lamp lighting device 10 includes a DC/AC conversion section 11 that boosts power supplied from a battery 13 to supply the boosted power to a discharge lamp, an I/F circuit 14 that divides a battery voltage to make a divided voltage and a microprocessor 15 which compares a threshold voltage with the divided voltage obtained by dividing the battery voltage by the I/F circuit to control the DC/AC conversion section, whereby can light and control the discharge lamp with high accuracy. SEMICONDUCTOR INTEGRATED CIRCUIT
