Abstract
A spike suppression circuit for filtering out voltage oscillation produced by an inductive component and a conversion control circuit are disclosed. The spike suppression circuit includes an energy release path and a detection circuit. One end of the energy release path is coupled to a connection terminal of a circuit, and the other end thereof is coupled to a reference voltage. The detection circuit is coupled to the connection terminal. The detection circuit has a high-pass component for turning on the energy release path when the voltage on the connection terminal has a high-frequency signal.
