A synchronous buck converter for supplying a LED load has a high side switch and a low side switch connected in series. An inductor is connected to the midpoint of these switches, and control circuitry controls the alternate switching operation of the two switches. The switches are controlled such that there are time periods in which a negative current is flowing through the low side switch, and a feedback signal indicating the level of the negative current is supplied to the control circuitry. A switching-off command is issued to the low side switch as soon as the feedback signal reaches or crosses a threshold value. A feedback signal from the LED load is fed back to the control circuitry, the control circuitry adapts its threshold value depending on the feedback signal.

Abrégé

The invention concerns a converter circuit for providing a load current to a load, in particular to a lighting device such as a LED lighting module. The converter circuit comprises at least one switch configured to switch between a conducting state and a non-conducting state based on a switch control signal. A current sense circuit of the converter circuit generates a current sense signal based on a sensed current via the switch. Based on the current sense signal, a control circuit of the converter circuit generates the switch control signal. The control circuit controls the switch to switch asynchronously from the conducting state to the non-conducting state when the current sense signal reaches a threshold value. The converter circuit is characterized by the control circuit setting a blanking time interval, wherein the blanking time interval starts at a time when the switch switches from the non-conducting state to the conducting state, and, during the blanking time interval, the control circuit inhibits switching the switch from the conducting state to the non-conducting state.

System and method for facilitating maintenance of an emergency lighting system (1) in which an operating device (5) is configured to at least temporarily operate a light source (4) from electrical energy stored in a rechargeable battery (3). System measurement values and/or events are repetitively determined during operation of the operating device (5) and stored in an internal memory (9) of the operating device (5). The oldest corresponding stored data is cyclically overwritten. At least part of the stored data is transferred to an external memory (12) at a plurality of different times thereby accumulating measurement values and/or information on events in the external memory (12). A processing means (13) analyses at least part of the accumulated measurement values and/or information on events to determine a state of at least one component of the emergency lighting system (1), and generates an indicator for the determined state. The determined state of the at least one component is signalled based on the indicator.

Concerning the field of power electronics and lighting, the method for controlling at least one driver device, in particular a light driver, controls the at least one driver device to operate either in a standby mode or in a power-supplying mode. The method comprises obtaining a parameter value, evaluating the obtained parameter value to determine whether the obtained parameter value meets a lifecycle-criterion, and switching the at least one driver device into a lifetime- preserving mode in case the obtained parameter value meets the lifecycle criterion. In the lifetime-preserving mode, an adjustable value of at least one operational parameter of the at least one driver device is set to reduce a temperature spread of a device temperature of the at least one driver device. A control circuit for a driver device, e.g. a light driver, the driver device, a luminaire or a lighting system may implement the method.
