ABSTRACT:
A driver circuit for driving capacitive loads comprises a regenerative high side driver and a low side driver. A boost circuit responsive to an input signal turns the regenerative high side driver on hard producing a very fast output rise time. A feedback circuit is provided which disables the boost circuit when the output voltage reaches a predetermined value conserving supply current. A sustaining resistor provides base current to maintain the high side driver on after the feedback circuit has disabled the boost circuit.
