Abstract

A floating driving circuit according to the present invention comprises an input circuit to receive an input signal. A latch circuit receives a trigger signal for generating a latch signal. The latch signal is used to turn on/off a switch. A coupling capacitor is connected between the input circuit and the latch circuit to generate the trigger signal in response to the input signal. A diode is connected from a voltage source to a floating supply terminal of the latch circuit for charging a capacitor. The capacitor is coupled between the floating supply terminal and a floating ground terminal of the latch circuit to provide a supply voltage to the latch circuit. The latch circuit is controlled by the input signal via the coupling capacitor.
