Description
technical field
[0001] The present invention relates to the field of electronic circuits, and more specifically, to a short circuit protection method and device for a voltage regulating circuit. Background technique
[0002] The existing pulse width voltage regulation circuit cannot control the abnormal short circuit from input to output, which can only be realized by the overvoltage protection function. However, the overvoltage protection function cannot distinguish whether the abnormality is caused by the decrease of the input voltage or the abnormality caused by the short circuit; and the overvoltage protection needs to avoid the false triggering caused by the peak glitch during the dynamic response, so the processing time is long and the efficiency is low.
[0003] Aiming at the problems of slow response, poor stability and low pertinence of the short-circuit protection function of the voltage regulation circuit in the prior art, there is no effective solution at present...
