Protection circuit for switching power amplifier |
摘要 |
A protection circuit for a switching power amplifier comprises a first detection circuit which detects a current flowing through an output stage switching circuit, a second detection circuit which detects an output voltage of the output stage switching circuit, and an amplitude limitation circuit which limits the amplitude of an input signal to the output stage switching circuit in accordance with both the first and second detection. Thus the switching circuit is surely protected from destruction.
