Abstract
Disclosed is an SMPS for preventing abnormal overcurrents. A circuit having a short circuit delay is used to generate a control signal for turning off a main switch (i.e., a switching MOS transistor) when the overcurrent occurs, that is, in an initial startup or when a protection circuit is operated. Accordingly, a drain-source voltage of the main switch is reduced when the main switch is turned off, and a switching MOS transistor with a low withstanding voltage can be used.
