Abstract
Driver with open output protection Starting current for a load driver () for driving a load (L) is provided via the load. In a load driver () for driving a load (L), an operating current or an operating voltage at a reference point is derived from a power voltage bus () by coupling said reference point to said power voltage bus via the load. A load driver () for driving a load (L) comprises an output capacitor () and two output terminals () coupled to the output capacitor. A coupling diode () is coupled in forward connection from one output terminal to a terminal of the output buffer capacitor. A startup terminal () of a converter circuit () is coupled to said one output terminal () to receive a startup current (Is) via the driven load if the load is present to conduct this current.
