OVERCURRENT PROTECTION CIRCUIT AND SWITCHING POWER APPARATUS USING THE SAME |
| 摘要 |
An overcurrent protection circuit includes a voltage monitoring part configured to monitor an output voltage generated from a periodic switching operation of a switching output stage or a feedback voltage corresponding to the output voltage, a current monitoring part configured to monitor whether a current flowing through the switching output stage is under an overcurrent condition, and a protection operation part configured to perform an overcurrent protection operation in response to monitoring results of both the voltage monitoring part and the current monitoring part. |
