  • Over-current protection for a switch mode class D audio amplifier
    Patent number: 8749303
    Abstract: 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.
    Type: Grant
