Switching regulator with fault protection and method thereof |
摘要 |
<p>A switching regulator with fault protection and method thereof. The switching regulator comprises a switching circuit, a control circuit, a fault detection circuit and a fault timer. The fault detection circuit is electrically coupled to the switching circuit to detect whether a fault condition exists and generate a fault signal accordingly. The fault timer starts to time once the fault signal becomes valid, and is reset when the fault signal becomes invalid. If the fault time reaches a first time threshold, the control circuit is disabled, and the switch in the switching circuit is turned off.
