Abstract
A constant current control is performed by PWM, and an analog burst control and a digital burst control are made selectable. The burst controls are selected in the following manner. A capacitor is selected as an element which is to be connected to a triangular signal oscillator circuit, to generate a triangular signal, thereby setting the analog burst control. A resistor is selected as the element to generate a constant voltage, thereby setting the digital burst control. A controller IC is used commonly in both the burst controls.
