发明名称 Audio power amplifier
摘要 A smart protection circuit to prevent possible circuit malfunction or damage due to sudden power source voltage fluctuation is introduced. In case of quick and large voltage fluctuation in power supply, a control signal is activated to stop power transistor switching. When power supply is stable at a lower or higher operating voltage, the switching circuit is able to return to normal operation.
