摘要： The present invention provides a driver circuit with load discharge detection particularly suitable for use with electro-luminescence (EL) lamps. The driver circuit determines the moment at which the load has been discharged by a defined discharge current. This information is used to start the new charging cycle of the load. The discharge time adapts itself to different load sizes or load voltages. Also, a minimum amount of time is used to discharge the load, so that a maximum amount of time is available for charging the load at a predetermined frequency. As a result, a higher performance can be achieved.
