OUTPUT SWITCHING CIRCUIT
First Claim
1. An output switching circuit comprising:
- a switching circuit having a first transistor connected to a high-voltage power supply, a second transistor connected to a low-voltage power supply, and an output terminal at a connection node between the first and second transistors;
a comparison unit that compares an input signal with a feedback signal obtained by feedback of an output signal of the output terminal via a low-pass filter to generate a comparison signal; and
a drive pulse generating unit that generates first drive pulses for driving the first transistor and second drive pulses for driving the second transistor in accordance with the comparison signal.
