Abstract:
A driver circuit for at least one light-emitting optoelectronic component includes a control circuit having a capacitor and a control switch, wherein the control switch electrically connects to the component such that the component is supplied with current by the capacitor as a function of a switching state of the control switch, and a charging circuit having at least a first charging switch, a bias resistor and a buffer capacitor, wherein the charging circuit electrically connects to the capacitor and is configured to charge the capacitor through the bias resistor, and the buffer capacitor is linked to a connecting line between the bias resistor and the capacitor.
