Circuit and method for reducing overshoot in a switching regulator |
摘要 |
<p>Output voltage overshoot of a switching regulator is controlled by deactivating switching operation when a signal proportional to the output voltage exceeds a variable threshold level, with the threshold level set as a function of regulator output current. In accordance with an embodiment, a difference signal is generated that corresponds to a difference between an output voltage feedback signal and a constant reference voltage. The generated difference signal is combined with a signal proportional to load current to obtain an adapted threshold level. The adapted threshold level is greater than the level of the constant reference voltage. A regulator switch is reset to an off state when the output voltage feedback signal exceeds the adapted threshold level.</p> |
