摘要: A detection resistor is arranged on a path of an LED string. A controller generates a gate pulse signal having a duty ratio adjusted such that the voltage drop at the detection resistor matches a predetermined reference voltage. Furthermore, the controller receives a dimming control signal which indicates the duty ratio of the burst dimming operation, and generates a corresponding burst dimming pulse. According to the gate pulse signal, the first driver drives an output circuit configured to generate a driving voltage. A second driver switches a path of a driving current between connection and disconnection according to the burst dimming pulse. A duty ratio detection unit controls the frequency of the gate pulse signal according to the duty ratio indicated by the dimming control signal.

摘要: A driving circuit is provided, which is configured to supply a driving voltage and a driving current to an LED string. A first detection resistor is arranged on a path of the LED string. A voltage source outputs a control voltage having a level that corresponds to the target luminance level of the LED string, and a first threshold voltage that is proportional to the control voltage. A controller generates a gate pulse signal having a duty ratio that is adjusted such that the voltage drop across the first detection resistor matches the control voltage. A first driver drives a switching transistor of a DC/DC converter according to the gate pulse signal. When the voltage drop across the first detection resistor exceeds the first threshold voltage, a first comparator stops the switching operation of the switching transistor.

摘要: A start-up circuit receives a start-up signal instructing start-up of an equipment mounted with the circuit, and executes a predetermined sequence when start-up is instructed by the start-up signal. An oscillator generates a clock signal. A sequence circuit receives the start-up signal and a clock signal output from the oscillator, measures time by counting the clock signal when the start-up signal transits to a predetermined level, and executes a predetermined event at a predetermined timing. The oscillator operates for a period where the start-up signal is at the predetermined level if the start-up signal is at the predetermined level during the period the power key of the equipment mounted with the circuit is being pushed.

摘要: There is a concern that water on the top surface of a cover 50A will penetrate the top face of a case 20 through gaps between an opening portion 51H and parts accommodation portions 34 because the parts accommodation portions 34 are exposed to the outside at the opening portion 51H on the top face of the cover 50A while the electrical connection box P is positioned in the cover 50A. Because drainage grooves 35 and 36, which reach the drainage channels 38 on the outside face of the case 20, are formed on the top face of the case 20, water that remains on the top face of the case 20 (the main body portion 30) is reliably drained by flowing into the drainage grooves 35 and 36.

摘要: A bulging wall portion, which forms a connector accommodation portion by bulging outward from a side wall, is formed in a cover plate portion of a cover. The bulging wall portion has an overhead wall formed such that it rises from the cover plate portion. A sloping wall is formed on the overhead wall such that roughly the center in the width direction of the connector accommodation portion serves as a vertex and the sloping wall slopes in downward gradients from the vertex toward both ends in the width direction. Water that flows down over the cover plate portion is caught by the overhead wall and flows downward along the sloping wall. The water is guided to both side faces on the outer sides in the width direction of the connector accommodation portion, so that it is drained off while avoiding the opening portions of the second through fourth connectors.
