Over-current protection for a switch mode class D audio amplifier |
摘要 |
<p>Circuits and methods for over-current protection of pulse-width modulation systems such as switch mode class D audio systems, DC-to-DC converters, or switch mode power supplies have been disclosed. Over-current protection has been achieved by introducing supply-scalable pulses to bring the modulation index of PWM pulses to a safe level. Additionally to the over-current protection a recovery circuit and method to be applied right after an over-current situation has been disclosed.</p> |
