Abstract: An information processing apparatus employs a liquid crystal display and a fluorescent lamp for backlighting the screen of the liquid crystal display. A lighting circuit for supplying alternating current lighting power to the fluorescent lamp receives input power from either a commercial alternating current power source or from a direct current battery. The level of the lighting power supplied to the fluorescent lamp is determined based upon a determination of whether the input power is being supplied from the commercial power source or from the battery.

Abstract: When a current that flows into a power output element is greater than a predetermined value, pulse width-modulated signals are formed which vary in inverse proportion to the current value in order to drive the power output element. When an excess current flows into the power output element, therefore, the power output element is allowed to intermittently operate for only short periods of time, and the current can be decreased during the current-limiting operation.
